Abstract

A new method for external stereotactic focal irradiation of three-dimensional irregular target volumes is proposed. In this method the target is irradiated by a linear accelerator set in various angular positions around the isocenter. During the irradiation the target is translated in a direction perpendicular to the beam. By controlling the velocity of the translation it is possible to modify the configuration of therapeutic isodoses so as to make them follow the borders of the target.

摘要

提出了一种用于三维不规则靶区体外立体定向聚焦照射的新方法。在该方法中，靶区由围绕等中心设置在不同角度位置的直线加速器进行照射。在照射过程中，靶区沿垂直于射束的方向平移。通过控制平移速度，可以改变治疗等剂量线的形态，使其与靶区边界相符。
