The evaluation of the quality of external radiotherapy plans in patients with cervical cancer was performed. There was analyzed homogeneity index in the target volume (PTV), conformity index and others for 53 patients. Homogeneity and conformity indexes within the tolerances were achievable in the clinic with the implementation of technology 3D CRT, IMRT and Rapid Arc. The rectum and the bladder dose for 38% of patients irradiated by -of IMRT and Rapid Arc methods was significantly less compared to the 3D CRT and was in average 31 Gy. This reflected the benefits of these technologies for radiation exposure to critical organs.
