摘要
改进了矩阵模型剂量算法.建立了射野矩阵、质心插值公式.提高了计算效率。该方法与AAPM55#测试结果及直接实验测量值进行比较和检验,结果表明,计算速度快,适合作为放射治疗计划系统的快速剂量算法。
The dose algorithm by matrix model has been modified. The jobs involved include the establishment of the matrix of field with the convenience and nicety to deal with every fields, and a formula on interpolation of cen- troid was brought forward to increase the precision of computation. Because of its higher calculating speed, the algo- rithm is suitable to the speediness of the treatment planning systems.
