Imrt boost plan
WitrynaTherefore, there are one to three charges of 77300 for a typical VMAT plan. In “step and shoot” or compensator based IMRT treatment courses, one unit of 77300 can be charged per gantry angle. Therefore, the units of 77300 charged would correspond to the number of gantry angles in the IMRT plan, frequently up to 10 units. WitrynaThe two common descriptors for IMRT are forward-planning “fields in field” and inverse planning. Unlike IMRT for other organs, the aim of IMRT for breast planning is to achieve dose homogeneity and not organ conformality. ...
