II.放射線治療における回転横断撮影の応用とその意義(高エネルギー照射装置による治療計画のあり方)(第1回放射線技術)

抄録

Subjects involved in tomographic equipment and techniques required for taking axial transverse tomogram suitable for diagnosis were summarized into four items and were explained, that is adjustment of axial transverse tomograph, application of moving filter, device for reducing obstractive shadow, tomography while changing the tube voltage. Axial transverse tomography is considered indispensable to the planning and implementation of radiation therapy. The contents were explained for cases of two oblique field irradiation, moving field irradiation, hollow out technique irradiation and high energy electron beam irradiation.
