Evaluation of skin dose under the bolus for post-operative breast cancer treatment

Results of investigation of the absorbed doses on a phantom surface under the “sticking” and ordinary non-sticking silicone boluses simulating post-operative breast cancer irradiation are presented in this paper. It is shown that the treatment effectiveness in post-operative breast cancer irradiation may be improved when a “sticking” bolus attached to the patient surface is applied instead of an ordinary non-sticking bolus. Application of “sticking” bolus adapted treatment configuration is of advantage because it is independent on air gaps between bolus and the surfaceKauno technologijos universitetasLSMUL VšĮ Kauno klinikų filialas Onkologijos ligoninėUAB "Medicinos fizika"Vytauto Didžiojo universitetasŽemės ūkio akademij
