THE GRADIENT STUDY OF RADIATION USING LINEAR ACCELERATOR BASED IN THE TREATMENT PLANS OF CARCINOMAS BY RADIOTHERAPY

Cancer is a widespread problem and concern throughout the globe. Almost half of cancer patients treat by radiation. Based on this, the aim of this research is concerned with the study of radiation doses, generated by the linear accelerator(LINAC) applied during cancer treatment in radiotherapy. To realize tumor treatment plan , is used source of energy photons 15 MV. The results obtained showed that the isodose distributions in tumor volumes includes tumor volume inside surface of isodoses D95 (%) and D90 (%) and safing the risk organs around the tumor volume in the percentage allowed.
