Geometric accuracy is critical for radiotherapy and is one major concern in the application of MRI in radiotherapy. Since the geometric distortion and B0 inhomogeneity are related, we aim to evaluate the geometric distortion due to ΔB0 variation at inhalation and exhalation breath-hold. Based on our results, larger geometric distortion was noted during inhalation than exhalation.
