Imrt breast
WitrynaIMRT is an advanced method of treatment planning and delivery. In contrast to 3D-CRT, IMRT uses inverse planning, meaning that target and normal tissue constraints describing the desired dose distribution are transferred to the planning software, which then uses algorithms to generate beam arrangements that best meet the objectives … WitrynaThe Cambridge Breast IMRT Trial is a randomized control trial (RCT) comparing 3D or FP FIF IMRT to 2D planning of two-field tangents for 815 randomized patients. 17 The …
