摘要
探讨了在Van de Geijn的计算机程序中减少屏蔽块的尺寸和位置的原始限制的可能性。提出了基于实验测量和更多理论方法的新方法,而无需对程序本身进行任何更改。提出了两个典型的临床例子,并对所获得的精度进行了严格的研究。
Reduction of the limitations for the calculations of shielding effects with Van de Geijn's computer program.
The possibilities for reducing in Van de Geijn's computer program the original limitations for the size and the position within the field of shielding blocks are explored. New methods are presented which are based on experimental measurements as well as more theoretical approaches, without need for any change in the program itself. Two typical clinical examples are presented and the precision obtained critically investigated.
