Table 1
(a) The doses of organs at risk in helical irradiation of the total skin (HITS) with dose painting technique. (b) The surface doses of skin from head to toes measured with radiochromic EBT2 film in helical irradiation of the total skin (HITS) with dose painting technique. (c) The mean values of registration with pretreatment and posttreatment using kVCT-MVCT fusion for helical irradiation of the total skin (HITS) with dose painting technique.
