摘　　要：目的探讨建立调强放疗个体化患者剂量的验证体系。方法使用IBA公司生产的0.65型电离室配合相应剂量仪DOSE1及验证模体进行绝对剂量的验证;用二维电离室矩阵MATRIXX进行相对剂量的验证。结果利用电离室在选定的参考点进行绝对剂量的验证,以此为基础,使用二维电离室矩阵进行相对剂量的验证,可以得出患者调强放疗计划执行的误差。结论该方法切实有效,简单可行,可作为建立调强放疗个体化患者剂量的验证体系。Objective To study how to build the system of IMRT individual patient dose verification. Methods The absolute dose verification can be planted by DOSE1 dosimeter and testing mode in the 0.65 ionization chamber of IBA Ltd Co,and the relative dose verification is used the two-dimensional ion chamber array. Results The absolute dose can be tested in the reference point through ionization chamber method. As a foundation, some errors of IMRT individual patient can be found by the two-dimensional ion chamber array method. Conclusion The method is effect, safe and easy. It＇s suitable to build the system of IMRT individual patient dose verification.
