Metals in computed tomography (CT) scans often saturate image pixel values, making low- and high-density metals indistinguishable. The purpose of this work was to test the effectiveness of the extended HU mode on a GE Discovery RT16 CT scanner to distinguish...

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...

High Dose Rate (HDR) brachytherapy requires a rapid turnaround from treatment planning to delivery. Medical physicists perform dose planning and quality assurance (QA) checks prior to treatment, but these tasks are time-consuming and involve repetitive manual...

Deviceless 4DCT (D4D) reconstruction relies on changes to patient anatomy, such as lung volume or external contour to generate a pseudo respiratory trace which is used to bin 4DCTs for use in radiotherapy planning. This poses a challenge due to the lack of an...

Optimize patient dose for Lung Cancer Screening (LCS) using local diagnostic reference levels (DRLs).

To assess the repeatability of brain white matter sodium concentration (TSC) measurements using 3T sodium MRI with the Fermat Looped Orthogonally Encoded Trajectories (FLORET) 3D spiral.
