Radiotherapy verification is the process that enables us to be certain in treating the tumor volume as planned. to ensuring that accurate radiation dose has been given to the correct region, so measures of geometric verification were done, this study was carried out in radiation and isotopes center of Khartoum (RICK) including 57 patients were female 30 represented (52.6%) and male 27 represented (47.4%). using Interactive Data Language IDL software to measure the dimension and length of each axis for all images. The results show that the mean of simulator in X-axis 9.68±4.64 and for treatment film X-axis was 9.64±4.52, and for Y-axis for simulator 9±3.45 and for treatment film 8.96±3.25. Using paired sample t-test show there is no significant differences between simulator and treatment film for X-axis, and between simulator and treatment film for Y-axis. The association between simulator and treatment film for X-axis was 0.96 mm/mm, and for Y-axis was 0.94 mm/mm. Linear regression results showed that the rate of association for the simulator (X-Axis) and Treatment film (X-Axis) increases by 0.313 mm, and the rate of association between simulator (Y-Axis) and Treatment film (Y-Axis) increases by 0.437 mm.
