Tool Development for Bolus Shaping in Radiation Therapy

During External-Beam Radiotherapy in cancer therapy, Bolus, a thick sheet of flexible material, is used to cover the skin surface in order to minimize damage healthy tissues. A significant problem of using bolus is air gaps generated between the bolus and patientÂ’s skin if an inaccurate shape of bolus was made. In this research, an efficient process of shaping and cutting bolus will be developed to improve the efficiency and efficacy of bolus forming in order to minimize the air gap. This new approach utilizes an unfolding and folding method.
