Abstract

We have investigated a bicentric stereotactic convergent beam irradiation technique for the treatment of irregularly shaped, especially elongated, target volumes. Depending on the size and shape of the target volume optimum values for the isocenter distance, collimator apertures and dose inhomogeneity have been determined which serve as starting parameters for the interactive optimization of dose distribution. The treatment planning system of the stereotactic unit SRS-200 (Philips) has been used to calculate the parameter tables. However, the presented results are also applicable to other stereotactic systems.

摘要

我们研究了一种用于治疗不规则形状，尤其是细长形靶区的双中心立体定向汇聚束照射技术。根据靶区的大小和形状，确定了等中心距离、准直器孔径和剂量不均匀性的最佳值，这些值作为剂量分布交互式优化的起始参数。立体定向单元SRS - 200（飞利浦）的治疗计划系统已用于计算参数表。然而，所呈现的结果也适用于其他立体定向系统。
