治療のための撮影法 : 電子線の制動X線による撮影

抄録

In case of superficial x-ray therapy the position and size of the field is decided on the treatment-bed by radiography with supervoltage x-ray, in order to coincide it with the tumor region accurately. On the contrary it is not necessary to use this procedure in electronbeam therapy, because the tumor is usually superficial and easily palpable. But I believe, that in electron therapy also it is important to know that the localization of the tumor, the beam direction and the relation between the tumor and the neighboring sensitive organs. Therefore I consider the same technical procedure by the use of secondary radiation (Bremsstrahlen) during electron beam therapy as the localization-radiography by supervoltage x-ray. In this paper my experimental results are described.
