Abstract

The aim of this investigation is the study of dose distribution during treatment of breast cancer. The idea is the comparison of dose distributions of 6MV photon's energy with 15 MV photon's energy in the cases of mastectomy, when the breast is not present in the body and in cases when the breast is present. In these cases, the Tumor Volume (TV) is larger than in mastectomy cases. We have used Dose Volume Histogram (DVH) for analysis of dose distributions. The results were different. In the cases when the tumor volume was larger, the photons with energy 15MV have given better dose distribution, as long as in cases of smaller tumor volume, when the dose distribution was worst and vice versa. The conclusion is that, in cases of patients with mastectomy is better to use photon's energy of 6MV, because the tumor volume is smaller, and as a result the dose distribution is better and vice versa for photons with energy 15MV.
