Many studies have been published about patient dose, but those data were classified by each organ or tissue. Actuarially, patient dose should be checked by each examined part of patient and each exposure equipment. In this paper, we measured absorbed dose at the depth of 0-200mm with the Mix-DP phantom. The phantom is made by tissue equivalent meterial and is designed to similitude abdominal part. Percentage Depth Dose (PDD) was calculated from these doses. Three single-phase generators and three three-phases generators were used in this measurement. These measurements were analyzed by each equipment, and consequently the clear difference of PDD between the exposure equipments was not found. As the result, we can estimate patient dose at a random depth by using PDD. Furthermore, we can easily know patient dose from the tube-voltage and current time product by the calculation including PDD.These data are very useful to manager patient dose on radiological diagnosis. en-copyright= kn-copyright= en-aut-name=NakagiriYoshitada en-aut-sei=Nakagiri en-aut-mei=Yoshitada kn-aut-name=中桐義忠 kn-aut-sei=中桐 kn-aut-mei=義忠 aut-affil-num=1 ORCID= en-aut-name=AzumaYoshiharu en-aut-sei=Azuma en-aut-mei=Yoshiharu kn-aut-name=東義晴 kn-aut-sei=東 kn-aut-mei=義晴 aut-affil-num=2 ORCID= en-aut-name=SibuyaKoichi en-aut-sei=Sibuya en-aut-mei=Koichi kn-aut-name=渋谷光一 kn-aut-sei=渋谷 kn-aut-mei=光一 aut-affil-num=3 ORCID= en-aut-name=GotoSachiko en-aut-sei=Goto en-aut-mei=Sachiko kn-aut-name=後藤佐知子 kn-aut-sei=後藤 kn-aut-mei=佐知子 aut-affil-num=4 ORCID= en-aut-name=MaruyamaToshinori en-aut-sei=Maruyama en-aut-mei=Toshinori kn-aut-name=丸山敏則 kn-aut-sei=丸山 kn-aut-mei=敏則 aut-affil-num=5 ORCID= en-aut-name=SugitaKatsuhiko en-aut-sei=Sugita en-aut-mei=Katsuhiko kn-aut-name=杉田勝彦 kn-aut-sei=杉田 kn-aut-mei=勝彦 aut-affil-num=6 ORCID= en-aut-name=SonoyamaMasayo en-aut-sei=Sonoyama en-aut-mei=Masayo kn-aut-name=園山真世 kn-aut-sei=園山 kn-aut-mei=真世 aut-affil-num=7 ORCID= en-aut-name=MoriokaYasuki en-aut-sei=Morioka en-aut-mei=Yasuki kn-aut-name=森岡泰樹 kn-aut-sei=森岡 kn-aut-mei=泰樹 aut-affil-num=8 ORCID= en-aut-name=InamuraKeiji en-aut-sei=Inamura en-aut-mei=Keiji kn-aut-name=稲村圭司 kn-aut-sei=稲村 kn-aut-mei=圭司 aut-affil-num=9 ORCID= en-aut-name=TaharaSeiji en-aut-sei=Tahara en-aut-mei=Seiji kn-aut-name=田原誠司 kn-aut-sei=田原 kn-aut-mei=誠司 aut-affil-num=10 ORCID= en-aut-name=UnoHirofumi en-aut-sei=Uno en-aut-mei=Hirofumi kn-aut-name=宇野弘文 kn-aut-sei=宇野 kn-aut-mei=弘文 aut-affil-num=11 ORCID= en-aut-name=KadohisaShigefumi en-aut-sei=Kadohisa en-aut-mei=Shigefumi kn-aut-name=門久繁文 kn-aut-sei=門久 kn-aut-mei=繁文 aut-affil-num=12 ORCID= en-aut-name=InoueTatsuya en-aut-sei=Inoue en-aut-mei=Tatsuya kn-aut-name=井上龍也 kn-aut-sei=井上 kn-aut-mei=龍也 aut-affil-num=13 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=14 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=2 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=3 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=4 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=5 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=6 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=7 en-affil= kn-affil= affil-num=8 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=9 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=10 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=11 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=12 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=13 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=14 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 en-keyword=医用放射線被曝 (patient dose) kn-keyword=医用放射線被曝 (patient dose) en-keyword=X線撮影条件 (X-ray exposure) kn-keyword=X線撮影条件 (X-ray exposure) en-keyword=線量測定 (Radiation dosimetry) kn-keyword=線量測定 (Radiation dosimetry) END start-ver=1.4 cd-journal=joma no-vol=96 cd-vols= no-issue=11-12 article-no= start-page=1205 end-page=1215 dt-received= dt-revised= dt-accepted= dt-pub-year=1984 dt-pub=19841230 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A clinical application of an alternate irradiation system kn-title=中心分割法の臨床的応用 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In 1979, we published an article about an alternate irradiation system in the Japanese Journal of Radiological Technology.

An electron-beam has the range depended on its energy, and its dose is rapidly decreased at the points beyond the range. This property is available to irradiating a tumor with leaving the critical organs unexposed. However, we should take notice that the dose-distributions are disordered if materials of various densities are in the irradiation field. In this paper, we examined how the dose-distribution are disordered by using the phantom made from human bones of various volumes. As a result, the peculiar disorders of the dose-distribution due to the difference of the bone width were found at the back and edge of a bone. Moreover, the dose at the edge of a bone was decreased, but the dose at the side of a bone was rapidly increased in the distance position from the bone. It is necessary to take account of that the above peculiar phenomenon affect the total dose for the treatment when bones exist near the target volume in the irradiation field. kn-abstract=電子線治療は,体表面またはその近傍に発生する悪性腫瘍の治療にしばしば用いられる治療法である｡電子線はエネルギーに対応した飛程を持っており,飛程を越えると急激に線量は減少する。この性質は腫瘍に一定の線量を照射し,腫瘍後方に存在する決定臓器を保護することができるので,病巣を選択的 に治療するのに好都合である｡しかし,照射野内に人体軌部組織より密度の違う物質が存在する場合,散乱,吸収の影響が大きく,電子線線量分布は乱れたものとなる｡今回,人体内にある骨を想定してVolumeの違う骨Phantomを使 用して影響を調べたところ,骨幅によって骨後方および断端に線量の乱れが生じることがわかった｡すなわち,骨の中央ではある程度後方に距離が離れると,線量は大きく減少する現象が見られた。また,横方向の線量分布は骨断端近くで一旦線量の減少が見られ,断端を離れると急激に増加する｡したがって,実際の臨床において,Target Volume近くに骨が存在する場合は総線量の決定に際して注意が必要である｡ en-copyright= kn-copyright= en-aut-name=NakagiriYoshitada en-aut-sei=Nakagiri en-aut-mei=Yoshitada kn-aut-name=中桐義忠 kn-aut-sei=中桐 kn-aut-mei=義忠 aut-affil-num=1 ORCID= en-aut-name=InamuraKeiji en-aut-sei=Inamura en-aut-mei=Keiji kn-aut-name=稲村圭司 kn-aut-sei=稲村 kn-aut-mei=圭司 aut-affil-num=2 ORCID= en-aut-name=TaharaSeiji en-aut-sei=Tahara en-aut-mei=Seiji kn-aut-name=田原誠司 kn-aut-sei=田原 kn-aut-mei=誠司 aut-affil-num=3 ORCID= en-aut-name=UnoHirofumi en-aut-sei=Uno en-aut-mei=Hirofumi kn-aut-name=宇野弘文 kn-aut-sei=宇野 kn-aut-mei=弘文 aut-affil-num=4 ORCID= en-aut-name=AzumaYoshiharu en-aut-sei=Azuma en-aut-mei=Yoshiharu kn-aut-name=東義晴 kn-aut-sei=東 kn-aut-mei=義晴 aut-affil-num=5 ORCID= en-aut-name=SibuyaKoichi en-aut-sei=Sibuya en-aut-mei=Koichi kn-aut-name=渋谷光一 kn-aut-sei=渋谷 kn-aut-mei=光一 aut-affil-num=6 ORCID= en-aut-name=GotoSachiko en-aut-sei=Goto en-aut-mei=Sachiko kn-aut-name=後藤佐知子 kn-aut-sei=後藤 kn-aut-mei=佐知子 aut-affil-num=7 ORCID= en-aut-name=MaruyamaToshinori en-aut-sei=Maruyama en-aut-mei=Toshinori kn-aut-name=丸山敏則 kn-aut-sei=丸山 kn-aut-mei=敏則 aut-affil-num=8 ORCID= en-aut-name=MoriokaYasuki en-aut-sei=Morioka en-aut-mei=Yasuki kn-aut-name=森岡泰樹 kn-aut-sei=森岡 kn-aut-mei=泰樹 aut-affil-num=9 ORCID= en-aut-name=SakaeKatsuyosi en-aut-sei=Sakae en-aut-mei=Katsuyosi kn-aut-name=栄勝美 kn-aut-sei=栄 kn-aut-mei=勝美 aut-affil-num=10 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=中川富夫 kn-aut-sei=中川 kn-aut-mei=富夫 aut-affil-num=11 ORCID= en-aut-name=TakemotoMitsuhiro en-aut-sei=Takemoto en-aut-mei=Mitsuhiro kn-aut-name=武本充広 kn-aut-sei=武本 kn-aut-mei=充広 aut-affil-num=12 ORCID= en-aut-name=SugitaKatsuhiko en-aut-sei=Sugita en-aut-mei=Katsuhiko kn-aut-name=杉田勝彦 kn-aut-sei=杉田 kn-aut-mei=勝彦 aut-affil-num=13 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=14 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医療技術短期大学部 affil-num=2 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=3 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=4 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=5 en-affil= kn-affil=岡山大学医療技術短期大学部 affil-num=6 en-affil= kn-affil=岡山大学医療技術短期大学部 affil-num=7 en-affil= kn-affil=岡山大学医療技術短期大学部 affil-num=8 en-affil= kn-affil=岡山大学医療技術短期大学部 affil-num=9 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=10 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=11 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=12 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=13 en-affil= kn-affil=岡山大学医療技術短期大学部 affil-num=14 en-affil= kn-affil=岡山大学医学部放射線医学教室 en-keyword=電子線治療 (electron-beam therapy) kn-keyword=電子線治療 (electron-beam therapy) en-keyword=線量分布 (dose distribution) kn-keyword=線量分布 (dose distribution) en-keyword=不均質物質 (inhomogeneity) kn-keyword=不均質物質 (inhomogeneity) END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=91 end-page=99 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=20020320 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=放射線エネルギーの違いによる喉頭癌における吸収線量の影響 kn-title=Influence of the dose to the laryngeal cancer by the difference in radiation beam energy en-subtitle= kn-subtitle= en-abstract=Tl声門癌に対して放射線治療を単独で行うのは確立している方法である｡しかし,頚部は解剖学的に複雑であり,前方に薄いX字形で,喉頭が気道に隣接している構造を持つので,病巣への線量はbuild-upとbuild-downの影響による線量低下が生じることが考えられる｡すなわち,放射線エネルギーの選択が喉頭癌の局所的制御に影響を及ぼすと言える｡この影響は,より高い放射線エネルギーでは,それに伴いより強く起きるということが基礎実験にて報告されている｡また,それらの線量測定は,熱ルミネセンス線量計(TLD)のような従来の測定システムで測定されていた｡しかし,空気空洞へTLD を単体 で浮かせ線量を正確に測定し評価を行うのは困難である｡本研究において,我々は Gafchromic MD-55 film (Nuclear Associates, Inc.)を使用し測定した｡ Gafchromic MD-55 film は,フィルムタイプ線量計でありエネルギー依存性がなく,3〜100 Gyを測定可能であり,アクリル製頸部ファントムの空気組織境界面及び,空洞部に線量計を容易に精度良く配置することが可能である｡また,この線量計は人体の軟部組織に近い組成である｡そこで, 4, 6および10MVの各エネルギーでこの線量計を用いてエネルギーの違いによる,頸部ファントムを用いて喉頭の線量評価を行った｡その結果,我々は,特に放射線エネルギー10MVで頸部ファントムにおける,前部組織-組織空洞境界面-空洞部の一連したbuild-upおよびbuild-downを線量計で評価することができた｡これらの研究の結果､前交連浸潤を有するT1-T2に相当する声門癌患者は,放射線エネルギー6MVおよび10MVではなく,4MVを用いることによって,より効果的な放射線治療を行えると推測できる。 kn-abstract=We investigated the usefulness of Gafchromic MD-55 film (Nuclear Associates, Inc.) for measuring the radiation doses on the radiotherapy of laryngeal cancers. Since larynx has thin wedge-shaped structure in anterior neck adjacent to airway, the radiation doses to the lesion may be diminished because of build-up and build-down. So, the dose has been measured with conventional measuring systems such as thermoluminescent dosimetry (TLD). However, it was not possible to evaluate the dose distribution correctly using TLD, because it is impossible to float a TLD chip in an air cavity. In this study, we employed Gafchromic MD-55 film as a dosimeter, for it can be set on the area of interest and with a measurability of dose range of 3 to 100 Gy, though it has no energy dependency. And this radiometer is composition near the soft tissue of the human body. The dose distributions to larynx were investigated with this film using neck phantom under each radiation beam energy of 4, 6 and 10 MV x-rays. Our neck phantom is made from acrylic resin and simulates a normal larynx on the basis of image information of computed tomography (CT). Moreover we observed secondary build-up and build-down curves in tissue in the vicinity of air cavities, especially at 10 MV x-rays. These findings suggest that patients with TI-T2 glottic cancers with anterior commissure invasion may receive more effective treatment with 4 MV x-rays rather than with 6 MV and 10 MV x-rays. en-copyright= kn-copyright= en-aut-name=AoyamaHideki en-aut-sei=Aoyama en-aut-mei=Hideki kn-aut-name=青山英樹 kn-aut-sei=青山 kn-aut-mei=英樹 aut-affil-num=1 ORCID= en-aut-name=NakagiriYoshitada en-aut-sei=Nakagiri en-aut-mei=Yoshitada kn-aut-name=中桐義忠 kn-aut-sei=中桐 kn-aut-mei=義忠 aut-affil-num=2 ORCID= en-aut-name=InoueMitsuhiro en-aut-sei=Inoue en-aut-mei=Mitsuhiro kn-aut-name=井上光広 kn-aut-sei=井上 kn-aut-mei=光広 aut-affil-num=3 ORCID= en-aut-name=InamuraKeiji en-aut-sei=Inamura en-aut-mei=Keiji kn-aut-name=稲村圭司 kn-aut-sei=稲村 kn-aut-mei=圭司 aut-affil-num=4 ORCID= en-aut-name=TaharaSeiji en-aut-sei=Tahara en-aut-mei=Seiji kn-aut-name=田原誠司 kn-aut-sei=田原 kn-aut-mei=誠司 aut-affil-num=5 ORCID= en-aut-name=UnoHirofumi en-aut-sei=Uno en-aut-mei=Hirofumi kn-aut-name=宇野弘文 kn-aut-sei=宇野 kn-aut-mei=弘文 aut-affil-num=6 ORCID= en-aut-name=MoriokaYasuki en-aut-sei=Morioka en-aut-mei=Yasuki kn-aut-name=森岡泰樹 kn-aut-sei=森岡 kn-aut-mei=泰樹 aut-affil-num=7 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=2 en-affil= kn-affil=岡山大学医学部保健学科放射線技術科学専攻 affil-num=3 en-affil= kn-affil=財団法人操風会岡山旭東病院放射線課 affil-num=4 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=5 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=6 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=7 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=8 en-affil= kn-affil=岡山大学医学部放射線医学講座 en-keyword=Gafchromic MD-55-2 film kn-keyword=Gafchromic MD-55-2 film en-keyword=radiation dose kn-keyword=radiation dose en-keyword=build-up kn-keyword=build-up en-keyword=build-down kn-keyword=build-down en-keyword=glottic cancer kn-keyword=glottic cancer END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=83 end-page=90 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=20020320 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Suitability on the densitometry systematize in Laser Densitometer Model 1710 for Gafchromic MD-55-2 film kn-title=Gafchromic MD-55-2 fi1mのLaser Densitometer Model 1710における線量計測体系上の適合性 en-subtitle= kn-subtitle= en-abstract=For the medical advancement, the speedy technical innovation is performed also in the radiotherapy. When patients can search for QOL (Quality of Life), the radiation therapy is one of the choices. The radiation therapy system for limited irradiation to lesion without affecting normal tissue has been developed over several years. On the technology of external irradiation in our country, the level is improving to clinical stage from study grade. In such things, a new requirement will come out also as for the measuring method of the medication dose. However, conventional various radiometers have many problems to the dosimetry of the new radiotherapy method. Gafchromic MD-55-2 film, which has new form of radiochromic film based on poly-diacetylene and has been introduced for medical applications recently, is expected to solve some problems. Now, in clinical usage of this film, there is no comprehensive guideline for densitometry system and it's calibration yet. So, in this paper, the densitometry of Gafchromic MD-55-2 film was performed with Laser Densitometer Model 1710 for general-purpose film dosimetry system. And then, problems in the densitometry were extracted and the accuracy of dosimetry was investigated. kn-abstract=医療の高度化に伴い,放射線治療分野においても急速な技術革新が行われている｡QOL(Quality of Life)を考慮に入れた治療が求められる多くの場合,放射線治療が大きな選択肢の一つであることは言うまでもない｡このような状況下の中で,正常組織に影響を与えず病巣に限局した放射線を照射する技術が開発され,外照射においては,欧米に習い我が国でも研究段階から臨床へ移り変わろうとしている｡その際に,投与線量評価を欠かすことができないが,従来から使用されているいずれの線量計も新しい治療法に対応しきれていない｡そこで,フィルムタイプ線量計, Gafchromic MD-55-2 film の開発により,いくつかの問題が解決されてきている｡しかし,この線量計を精度良く測定する濃度測定器が必要になるが,現段階において規格化されたガイドラインが存在しないのが現状である｡そこで本研究では,当施設で保有している]線フィルム線量測定用 Laser Densitometer Model 1710 を用いて Gafchromic MD-55-2 fllm による線量測定を行い,問題点の抽出を行うとともに線量測定精度の考察を行った｡ en-copyright= kn-copyright= en-aut-name=AoyamaHideki en-aut-sei=Aoyama en-aut-mei=Hideki kn-aut-name=青山英樹 kn-aut-sei=青山 kn-aut-mei=英樹 aut-affil-num=1 ORCID= en-aut-name=NakagiriYoshitada en-aut-sei=Nakagiri en-aut-mei=Yoshitada kn-aut-name=中桐義忠 kn-aut-sei=中桐 kn-aut-mei=義忠 aut-affil-num=2 ORCID= en-aut-name=InoueMitsuhiro en-aut-sei=Inoue en-aut-mei=Mitsuhiro kn-aut-name=井上光広 kn-aut-sei=井上 kn-aut-mei=光広 aut-affil-num=3 ORCID= en-aut-name=InamuraKeiji en-aut-sei=Inamura en-aut-mei=Keiji kn-aut-name=稲村圭司 kn-aut-sei=稲村 kn-aut-mei=圭司 aut-affil-num=4 ORCID= en-aut-name=TaharaSeiji en-aut-sei=Tahara en-aut-mei=Seiji kn-aut-name=田原誠司 kn-aut-sei=田原 kn-aut-mei=誠司 aut-affil-num=5 ORCID= en-aut-name=UnoHirofumi en-aut-sei=Uno en-aut-mei=Hirofumi kn-aut-name=宇野弘文 kn-aut-sei=宇野 kn-aut-mei=弘文 aut-affil-num=6 ORCID= en-aut-name=MoriokaYasuki en-aut-sei=Morioka en-aut-mei=Yasuki kn-aut-name=森岡泰樹 kn-aut-sei=森岡 kn-aut-mei=泰樹 aut-affil-num=7 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=2 en-affil= kn-affil=岡山大学医学部保健学科放射線技術科学専攻 affil-num=3 en-affil= kn-affil=財団法人操風会岡山旭東病院放射線課 affil-num=4 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=5 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=6 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=7 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=8 en-affil= kn-affil=岡山大学医学部放射線医学講座 en-keyword=Gafchromic MD-55-2 film kn-keyword=Gafchromic MD-55-2 film en-keyword=Laser Densitometer Model 1710 kn-keyword=Laser Densitometer Model 1710 en-keyword=濃度測定器制御ソフトウェア (Control software of densitometry system) kn-keyword=濃度測定器制御ソフトウェア (Control software of densitometry system) en-keyword=測定精度 (Accuracy of measurement) kn-keyword=測定精度 (Accuracy of measurement) END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=23 end-page=29 dt-received= dt-revised= dt-accepted= dt-pub-year=2003 dt-pub=20031225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Characteristic of GAFCHROMIC XR TYPE T dosimetry film kn-title=線量測定用GAFCHROMIC XR TYPE Tの特性 en-subtitle= kn-subtitle= en-abstract=In recent years, interventional radiology (IVR) using which uses prolomged fluoroscopy has been performed frequently in clinical radiology.

It is not easy to regulate those points by the control panel, however, for the equipment that is conventinally used for electron beam, theoretically, is to exchange lead (Pb), which is ordinarily used, to a low atomic number material as a scattering foil. We examined several different kinds and / or various thickness as a scattering foil material that can make the electron beam lower without an increase of the contaminant as X-ray. We hereby reported the results, and strongly suggested the following two materials in use; acrylic plate, carbon board, and so on, which are easily available and worked, would be practically useful for the total skin electron beam therapy. en-copyright= kn-copyright= en-aut-name=NakagiriYoshitada en-aut-sei=Nakagiri en-aut-mei=Yoshitada kn-aut-name=中桐義忠 kn-aut-sei=中桐 kn-aut-mei=義忠 aut-affil-num=1 ORCID= en-aut-name=MimuraSeiiti en-aut-sei=Mimura en-aut-mei=Seiiti kn-aut-name=三村誠一 kn-aut-sei=三村 kn-aut-mei=誠一 aut-affil-num=2 ORCID= en-aut-name=InamuraKeiji en-aut-sei=Inamura en-aut-mei=Keiji kn-aut-name=稲村圭司 kn-aut-sei=稲村 kn-aut-mei=圭司 aut-affil-num=3 ORCID= en-aut-name=TaharaSeiji en-aut-sei=Tahara en-aut-mei=Seiji kn-aut-name=田原誠司 kn-aut-sei=田原 kn-aut-mei=誠司 aut-affil-num=4 ORCID= en-aut-name=MiyakeHideaki en-aut-sei=Miyake en-aut-mei=Hideaki kn-aut-name=三宅英昭 kn-aut-sei=三宅 kn-aut-mei=英昭 aut-affil-num=5 ORCID= en-aut-name=AzumaYoshiharu en-aut-sei=Azuma en-aut-mei=Yoshiharu kn-aut-name=東義晴 kn-aut-sei=東 kn-aut-mei=義晴 aut-affil-num=6 ORCID= en-aut-name=EgusaTomomi en-aut-sei=Egusa en-aut-mei=Tomomi kn-aut-name=江草具視 kn-aut-sei=江草 kn-aut-mei=具視 aut-affil-num=7 ORCID= en-aut-name=MikamiYasutaka en-aut-sei=Mikami en-aut-mei=Yasutaka kn-aut-name=三上泰隆 kn-aut-sei=三上 kn-aut-mei=泰隆 aut-affil-num=8 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=9 ORCID= en-aut-name=YamadaToshiharu en-aut-sei=Yamada en-aut-mei=Toshiharu kn-aut-name=山田俊治 kn-aut-sei=山田 kn-aut-mei=俊治 aut-affil-num=10 ORCID= en-aut-name=SugitaKatsuhiko en-aut-sei=Sugita en-aut-mei=Katsuhiko kn-aut-name=杉田勝彦 kn-aut-sei=杉田 kn-aut-mei=勝彦 aut-affil-num=11 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=2 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=3 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=4 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=5 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=6 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=7 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=8 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=9 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=10 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=11 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 en-keyword=電子線エネルギー kn-keyword=電子線エネルギー en-keyword=X線混入率 kn-keyword=X線混入率 en-keyword=電子線全身照射法 kn-keyword=電子線全身照射法 en-keyword=スキャタリングホイル kn-keyword=スキャタリングホイル END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue= article-no= start-page=63 end-page=71 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=19920205 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Dose Distributions at Standard Diagnostic X-Ray Energy kn-title=撮影X線領域での線量分布 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Exposure dose has been indicated by surface dose or transit dose, but they could not indicate dose distributions inside the body. Modulex as the radiation therapy planning system was used for dose distributions at standard diagnostic X-ray energy. X-ray is low energy X-ray at standard diagnostic radiography, so alterations of the energy and the scattering dose distribution by absorbers are quite different from those at high energy X-rays. Mix-DP was put to the homogeneous tissue use, then Bone equivalent phantom or Lung equivalent phanton was put to the inhomogeneous tissue use. Density correction factors for inhomogeneous phantoms were gotten by the calculation of the water equivalent thickness. In Bone the inhomogeneous correction depended strongly on the bone thickness. In Lung it was in need of one density correction factor and the scattering correction method for the decrease of the back scattering. The calculated dose distributions by Modulex agreed with measured data when each correction was carried out, and it was indicated that those data apply to inclinical situations. en-copyright= kn-copyright= en-aut-name=MiyakeHideaki en-aut-sei=Miyake en-aut-mei=Hideaki kn-aut-name=三宅英昭 kn-aut-sei=三宅 kn-aut-mei=英昭 aut-affil-num=1 ORCID= en-aut-name=InamuraKeiji en-aut-sei=Inamura en-aut-mei=Keiji kn-aut-name=稲村圭司 kn-aut-sei=稲村 kn-aut-mei=圭司 aut-affil-num=2 ORCID= en-aut-name=NakagiriYoshitada en-aut-sei=Nakagiri en-aut-mei=Yoshitada kn-aut-name=中桐義忠 kn-aut-sei=中桐 kn-aut-mei=義忠 aut-affil-num=3 ORCID= en-aut-name=KadohisaShigefumi en-aut-sei=Kadohisa en-aut-mei=Shigefumi kn-aut-name=門久繁文 kn-aut-sei=門久 kn-aut-mei=繁文 aut-affil-num=4 ORCID= en-aut-name=MikamiYasutaka en-aut-sei=Mikami en-aut-mei=Yasutaka kn-aut-name=三上泰隆 kn-aut-sei=三上 kn-aut-mei=泰隆 aut-affil-num=5 ORCID= en-aut-name=AzumaYoshiharu en-aut-sei=Azuma en-aut-mei=Yoshiharu kn-aut-name=東義晴 kn-aut-sei=東 kn-aut-mei=義晴 aut-affil-num=6 ORCID= en-aut-name=YamadaToshiharu en-aut-sei=Yamada en-aut-mei=Toshiharu kn-aut-name=山田俊治 kn-aut-sei=山田 kn-aut-mei=俊治 aut-affil-num=7 ORCID= en-aut-name=SugitaKatsuhiko en-aut-sei=Sugita en-aut-mei=Katsuhiko kn-aut-name=杉田勝彦 kn-aut-sei=杉田 kn-aut-mei=勝彦 aut-affil-num=8 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=2 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=3 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=4 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=5 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=6 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=7 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=8 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=9 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 en-keyword=Exposure Dose kn-keyword=Exposure Dose en-keyword=Dose Distribution kn-keyword=Dose Distribution en-keyword=Radiation Therapy Planning System kn-keyword=Radiation Therapy Planning System en-keyword=Density Correction kn-keyword=Density Correction en-keyword=Scattering Correction kn-keyword=Scattering Correction END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=23 end-page=27 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=19960930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Basic properies of beam flatness analyzer (THEBES 7000) kn-title=ビームフラットネスアナライザ（7000型 THEBES)の基礎的性能の検討 en-subtitle= kn-subtitle= en-abstract=Lrradiation, which is one of the effective therapies to Cancer, is required to be accurate within ±5% of the tolerable error of the total system. An accurate dose has to be irradiated accurately at a target volume. For that Quality Control of the irradiation equipment is cotinually important. As the measurement of Beam Flatness is an important item, it is obligated to be measured once a week. In this paper as we have an opportunity to use a Beam Flatness Analyzer sold on a corporation of medical instrument, we experiment about the difference of sensitivity of mutual Chamber which is its basic property, the reproducibility of the measured score, and the minimum value of measuralbe dose. We find that the difference in every item is so small that its data is very reliable in a daily use. kn-abstract=癌の有力な治療法の1つである放射線治療はシステム全体の許容誤差が±5％と、正確な治療が要求されている。正確な線量を正確な場所に照射されなければならない。そのためには日頃から照射装置のQuality Control が重要である。Beam平坦度の測定はその中でも、重要な項目で1／6月の測定頻度が勧告されている。今回、市販のBeam Flatness Analyzer (7000型 THEBES) を使用する機会を得たので、その基礎的性能であるChamber 相互の感度のちがい、測定値の再現性、識別可能な最小線量について実験を行った。各項目とも誤差が非常に少なく、日常の使用に際してそのデータは十分信頼できるものであることがわかった。 en-copyright= kn-copyright= en-aut-name=NakagiriYoshitada en-aut-sei=Nakagiri en-aut-mei=Yoshitada kn-aut-name=中桐義忠 kn-aut-sei=中桐 kn-aut-mei=義忠 aut-affil-num=1 ORCID= en-aut-name=OguriNobuhiro en-aut-sei=Oguri en-aut-mei=Nobuhiro kn-aut-name=小栗宣博 kn-aut-sei=小栗 kn-aut-mei=宣博 aut-affil-num=2 ORCID= en-aut-name=MaruyamaToshinori en-aut-sei=Maruyama en-aut-mei=Toshinori kn-aut-name=丸山敏則 kn-aut-sei=丸山 kn-aut-mei=敏則 aut-affil-num=3 ORCID= en-aut-name=OkawaYoshihiro en-aut-sei=Okawa en-aut-mei=Yoshihiro kn-aut-name=大川義弘 kn-aut-sei=大川 kn-aut-mei=義弘 aut-affil-num=4 ORCID= en-aut-name=WakasaHiroyuki en-aut-sei=Wakasa en-aut-mei=Hiroyuki kn-aut-name=若狭弘之 kn-aut-sei=若狭 kn-aut-mei=弘之 aut-affil-num=5 ORCID= en-aut-name=NagayaIsao en-aut-sei=Nagaya en-aut-mei=Isao kn-aut-name=永谷伊佐雄 kn-aut-sei=永谷 kn-aut-mei=伊佐雄 aut-affil-num=6 ORCID= en-aut-name=AzumaYoshiharu en-aut-sei=Azuma en-aut-mei=Yoshiharu kn-aut-name=東義晴 kn-aut-sei=東 kn-aut-mei=義晴 aut-affil-num=7 ORCID= en-aut-name=ShibuyaKoichi en-aut-sei=Shibuya en-aut-mei=Koichi kn-aut-name=渋谷光一 kn-aut-sei=渋谷 kn-aut-mei=光一 aut-affil-num=8 ORCID= en-aut-name=GotoSachiko en-aut-sei=Goto en-aut-mei=Sachiko kn-aut-name=後藤佐知子 kn-aut-sei=後藤 kn-aut-mei=佐知子 aut-affil-num=9 ORCID= en-aut-name=MikamiYasutaka en-aut-sei=Mikami en-aut-mei=Yasutaka kn-aut-name=三上泰隆 kn-aut-sei=三上 kn-aut-mei=泰隆 aut-affil-num=10 ORCID= en-aut-name=InamuraKeiji en-aut-sei=Inamura en-aut-mei=Keiji kn-aut-name=稲村圭司 kn-aut-sei=稲村 kn-aut-mei=圭司 aut-affil-num=11 ORCID= en-aut-name=MoriokaYasuki en-aut-sei=Morioka en-aut-mei=Yasuki kn-aut-name=森岡泰樹 kn-aut-sei=森岡 kn-aut-mei=泰樹 aut-affil-num=12 ORCID= en-aut-name=SugitaKatsuhiko en-aut-sei=Sugita en-aut-mei=Katsuhiko kn-aut-name=杉田勝彦 kn-aut-sei=杉田 kn-aut-mei=勝彦 aut-affil-num=13 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=14 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=2 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=3 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=4 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=5 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=6 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=7 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=8 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=9 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=10 en-affil= kn-affil=三井病院放射線科 affil-num=11 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=12 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=13 en-affil= kn-affil=岡山大学医療技術短期大学部診療放射線技術学科 affil-num=14 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 en-keyword=放射線治療 (radiation therapy) kn-keyword=放射線治療 (radiation therapy) en-keyword=ビーム平坦度 (beam flatness) kn-keyword=ビーム平坦度 (beam flatness) en-keyword=性能評価 (valuation of property) kn-keyword=性能評価 (valuation of property) en-keyword=電子加速器 (electron accelerator) kn-keyword=電子加速器 (electron accelerator) END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue= article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=19910325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Total Skin Electron Beam Therapy kn-title=電子線全身照射法の検討 en-subtitle= kn-subtitle= en-abstract=皮膚に限局した一連の末梢型T細胞リンパ腫は放射線に対する感受性が高く、電子線治療の適応となる疾患である。こららの疾患は一般的に全身の皮膚に浸潤するため、治療に際してはTarget Volumeの深さに合わせた最小限のエネルギーで全身隈なく照射する必要がある。筆者等は最近臨床で遭遇した菌状息肉症の患者を治療するため、その患者に合った物理的なデータを測定した。照射野の拡大には振子照射法を用い、エネルギー低減方法は装置に装備されている鉛のスキャタラーを低原子番号で、しかも加工のしやすい塩化Vinyl板に交換する方法を工夫した。データとして治療効果、副作用に関係する線量率、エネルギー、及び照射野内平坦度について測定した結果、距離が長くなる関係から線量率が低下する全身照射法の欠点は解消できなかったが、エネルギー及び平坦度については使用可能なデータを得ることができた。 kn-abstract=The peripherally T-cell lymphoma; Mycosis fungoides etc, has the good radiation sensitivity, and has been adapted for total skin electron beam therapy.
