Abstract:
To investigate the patient-specific dose verification method using ArcCHECK for total marrow irradiation (TMI) with Volumetric Modulated Arc Therapy(VMAT) and Helical Tomotherapy(HT) . The kVCT images col ected from 8 patients were respectively designed for RapidArc and Tomotherapy plans in total marrow irradiation. ArcCHECK was used for dose verification for the head-neck, chest-abdomen and pelvic. The merging function of ArcCHECK was used in VMAT and the method of double plans(reference and delivery plans) were used in HT. The γ-analysis passing rates for the head-neck, chest-abdomen, pelvic were 98.9%±1.9%, 98.4%±1.8%, 97.4%±2.1% for VMAT plans and 94.3%±1.5%, 96.5±1.2%, 94.1%±1.9% for HT plans. The results show that using the merging function of ArcCHECK can achieve the dose verification wel for VMAT plans with TMI, The method of double plans was done for the dose verification of HT plans with TMI as wel as the plans with the targets keeping away from the set-up center.
