ABSTRACT
Objective To evaluate the dosimetric differences of one RapidPlan Model on different Radiotherapy devices.Methods A RapidPlan Model was built based on 30 reoptimization IMRT plans of cervical cancer patients on typeA LA.Dosimetric differences of automatic optimized IMRT plans using this model on 4 different type LAs,named respectivelyA,B,C andD,were compared with 12 test cervical cancer cases.These four LAs were well commissioned in the treatment planning system (TPS).Student t test was applied for statistical analysis on dosimetric differences.Results Dosimetric differences between A vs.B,C and D were observed on Dmean,HI,CI of PTV50 and PTV45,as well as on V50,V40,V30 of rectum and bladder.Significant dosimetric differences were observed between A and D (P<0.05).Conclusions Automatic planning with RapidPlan model may result in dosimetric differences on different Radiotherapy devices.These differences should be aware of with caution in its clinical application.
