目的 验证逆向调强治疗计划系统的物理精度。方法 用胶片和电离室测量 ,检测MLC的形状符合度、空间点的绝对吸收剂量、等剂量曲线符合度、剂量强度分布符合度 ,来验证逆向调强治疗计划的精度。结果 逆向治疗计划系统符合临床要求。
Objective To verify the physical accuracy of the reverse osmosis treatment planning system. Methods The accuracy of the reverse osmosis treatment planning was verified by film and ionization chamber measurements, shape compliance of MLCs, absolute absorbed dose at space points, coincidence of isodose curves and coincidence of dose intensity distributions. Results The reverse treatment planning system met the clinical requirements.
