Dynamic conformal irradiation (ark therapy)
In dynamic conformal method, conformality is low, irradiation dose fall especially at the end of an irradiation field. Hot point is usually generated in a anterior side. Because DMU (dose output value) is constant during gantry rotation in single phase. The distance from a skin surface and also the size of an irradiation field change in each direction. However, DMU is a fixed value.
I have not used 'dynamic conformal irradiation'. My templates are made with 'rectangular static field' for rotational port(s).
DMU is constant
