放射線治療システムを考える : 3 次元照射治療システムについて

抄録

In these days, technical inovations of medical accelerators including especially linear accelerators have much improved accuracy and repeatability of radiation delivery systems. On the other hands, a PACS which deals with storing and archivs of advanced medical diagnostic images by electronic comunication systems has been remarkablly improved and entered its routine use. These technologies are studied and become made good use of for the purpose of three dimensional radiation treatment planning systems and high energy X-ray real time imaging and its image prossecing veryfication systems. When we discuss radiotherapy systems, not only technical and academic issues but also economic, safety and confortable system development for patients should be taken into account. As the results, the improvements of reliability and safety should be primary discussed. Accordingly computer and three dimensional imaging applications and IEC standards become to play important role. These improvements affect the radiation oncology and the interdisciplinary and multimodal radiotherapy becomes realistic and ecconomical. In addition, recent characteristic technical issues are sumerized and tried to give appropliate solutions including a three dimensional radiation delivery system.
