Magnetic resonance imaging (MRI) is an important tool for visualizing tumor sites and organs at risk during spine radiation treatment planning. Some people with spinal metastasis require pedicle screw fixation to stabilize the spinal column which causes metal...

Magnetic resonance (MR) imaging is routinely used to contour targets for stereotactic radiotherapy planning. However, MR images can suffer from susceptibility-induced geometric distortions, especially near air-tissue interfaces. The objective of this work is...
