WitrynaIMRT is generally delivered with MLC-equipped linacs using either a static or a dynamic approach with moving leaves. In the latter approach the beams can be delivered without, or concurrently with gantry rotation (intensity-modulated arc therapy, IMAT). Witryna3 kwi 2024 · A pre-treatment PSQA program is a routine procedure in IMRT and, to some extent, can avoid serious errors in dose delivery. However, there is no guarantee that the dose delivered to the patient is the same as planned, due to the patient's anatomical change, setup uncertainty, and organ motion during treatments.
