Rotational IMRT (VMAT / RapidArc)

 Volume-modulated Arc Therapy (VMAT)  Efficient delivery in a single gantry arc

 High dose conformation/modulation  using a full 360 deg range of gantry rotation  Engineer dose computation to support accurate high- resolution sampling of all beam directions during planning.  Planning includes “ efficiency constraints ” to coordinate:  leaf motion/speed  gantry speed  dose rate.
