Abstract
Verification of the irradiation set up is a process to ensure that the position and volume of the irradiated tumor are the same as planned. It conducted by comparing the radiographic image information of the Treatment Planning System (TPS) with radiation therapy to be provided on the Electronic Portal Imaging Device (EPID). Existing software on the EPID modality device in this hospital are Mosaiq and IViewGT. This study was to describe the details of the verification process and the differences between two software in conformal radiotherapy of nasopharyngeal cancer patients. This study was a quantitative analytic study. Samples were fifty-two portal images. Data analyzed by statistical software. The results are descriptions of the verification process, and the value of shift set up irradiation on X; Y and Z axis. There is no difference statistically between two software. Mosaiq software is more complicated in image processing. IViewGT software has an advantage in more simple but shows the same quality.
