A computer program for checking photon external beam dose calculations is described. It provides a check of the treatment planning calculation by the use of machine data that are independent of that used in the initial calculation. Data required to specify any radiation beam are easily and rapidly set up and the program works for all the major manufacturers' machines. The user interface uses an interactive screen for machine data input and also for dose checking, where dose calculation is performed in real time as data are entered. The dose resulting from the planned field parameters is calculated and compared with the prescribed dose with a warning provided if the agreement is outside a set range (+/-5%). Its purpose is to act as a final quality assurance check to ensure that no significant errors occur in the monitor unit calculation.
描述了一种用于检查光子外照射剂量计算的计算机程序。它通过使用与初始计算中所使用的数据无关的机器数据来检查治疗计划计算。指定任何辐射束所需的数据易于快速设置，并且该程序适用于所有主要制造商的机器。用户界面使用交互式屏幕进行机器数据输入以及剂量检查，在输入数据时实时进行剂量计算。根据计划野参数计算出的剂量与处方剂量进行比较，如果二者的一致性超出设定范围（±5%），则会发出警告。其目的是作为最终的质量保证检查，以确保在监测单位计算中不会出现重大错误。
