Abstract
The dose distribution in photon beams from a 42 MeV betatron using wedge filters of lead with different angles of slope is described. The wedge coefficient to be considered at a field size of 10 X 10 cm is given. The scope for isodoses modified by wedge filters is discussed with regard to stationary-field photon therapy.
摘要
描述了使用不同倾斜角度的铅楔形滤过器时，42兆电子伏电子感应加速器产生的光子束中的剂量分布情况。给出了在10×10厘米射野尺寸下应考虑的楔形系数。针对固定野光子治疗，讨论了楔形滤过器对等剂量线的影响范围。
