Abstract

Static and dynamic multileaf collimation have been so far identified as two fundementally different methods of intensity modulation in radiotherapy. In multiple static collimation, the desired fluence is deposited using two steps: In the first step, the leaves (and the backup diaphragms if available) are moved to create the desired field, but no radiation is delivered in this step. In the second step, the beam is turned on, but no leaf motion occurs. This process is repeated for each static field until the desired fluence deposition has been obtained. This type of delivery has been chiefly used for the delivery of plans with constant fluence levels over several contiguous bixels.
