Abstract
A compensator made of a tungsten-based rod matrix has been proposed for small-field intensity modulated radiation therapy. The compensator was attached to a 6 MV linac gantry head. The proposed compensator could modulate the X-ray intensity with a step of 10% and a minimum transmission of 2.5%.
摘要
一种由钨基棒状矩阵制成的补偿器已被提出用于小射野调强放射治疗。该补偿器被安装在一台6兆伏直线加速器的机架头上。所提出的补偿器能够以10%的步长和2.5%的最小透射率来调制X射线强度。
