3D dose reconstruction: banding artefacts in cine mode EPID images during VMAT delivery
conference contribution
posted on 2025-05-10, 10:13 authored by H. C. Woodruff, Peter GreerPeter GreerCine (continuous) mode images obtained during VMAT delivery are heavily degraded by banding artefacts. We have developed a method to reconstruct the pulse sequence (and hence dose deposited) from open field images. For clinical VMAT fields we have devised a frame averaging strategy that greatly improves image quality and dosimetric information for three-dimensional dose reconstruction.
