Dosimetric Impact of Using a Virtual Couch Shift for Online Correction of Setup Errors for Brain Patients on an Integrated High-Field Magnetic Resonance Imaging Linear Accelerator.

Abstract

PURPOSE To quantify the dosimetric impact of using virtual couch shift (VCS) for correcting setup errors in glioblastoma multiforme (GBM) patients treated on a magnetic resonance imaging (MRI)-linac. METHODS AND MATERIALS Six GBM patients treated with 60 Gy (30 fractions) were selected for this simulation study. For each case, 2 reference plans were… (More)
