A modified irradiation technique at a linear accelerator facility for radiation surgery within the brain is described consisting of several moving field irradiations in non-coplanar planes. Using collimated narrow beams, a localization system and special computer programs for precise patient positioning, a high concentration of dose within small, well circumscribed volumes is obtained. Resulting dose distributions were studied experimentally and by calculations. A simple algorithm for treatment planning was developed and based on CT images. Radiation surgery within the brain is now technically feasible at our linear accelerator. Seventeen patients have now been treated.
描述了一种用于脑部放射外科手术的直线加速器设施的改良照射技术，该技术由在非共面平面内的几次移动野照射组成。使用准直窄束、定位系统和用于精确患者定位的特殊计算机程序，可在小的、边界清晰的体积内获得高剂量集中。通过实验和计算研究了所得的剂量分布。开发了一种基于CT图像的简单治疗计划算法。在我们的直线加速器上，脑部放射外科手术目前在技术上是可行的。现在已经治疗了17名患者。
