MRI simulation: effect of gradient distortions on three-dimensional prostate cancer plans

Purpose : To quantify the dosimetric consequences of external patient contour distortions produced on low-field and high-field MRIs for external beam radiation of prostate cancer. Methods and Materials : A linearity phantom consisting of a grid filled with contrast material was scanned on a spiral C...
