The delivery of IMRT calculated dose profiles can be achieved in two ways: MLC or fixed / solid beam modifiers. The MLC is known for its authomatic set‐ups. Looking at the total time for dose delivery, the fixed beam modifier technique shows lower total treatment per patient. Similar and different clinical studies has clearly demonstrated that solid beam modifiers are much superior to MLC when resolution of the calculated smooth fluence map is tested. The QA for fixed beam modifiers is less demanding than for MLC. Please study solid beam modifier vs MLC sheet describing these vital parameters.
