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...
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...
