Reduction of Dose Calculation Errors For Patients With Metal Implants Receiving Photon Radiation Therapy
… receiving external beam radiation therapy have metal implants that can affect their treatment, and these metal implants can degrade the accuracy of dose calculations. Dose calculation errors result from limitations of modern dose calculation algorithms in modeling metal/tissue interface effects. …

Characterization of metal artifacts in diffusion tensor imaging for spinal cord applications
… in DTI of the spinal cord is the presence of metal which causes geometric distortions, signal pile-up, and signal voids. Because most patients with spinal cord injury have some amount of metal hardware implanted for stabilization, it is important to confront issues involving metal as DTI of …

Development of A Ct Metal Artifact Management Algorithm For Proton Therapy Planning (Ampp) For Head and Neck Cancer Patients
… (high Z materials) are common sources of artifacts in Head and Neck (HN) images. Commercial artifact reduction techniques have been offered, but many are impractical, produce inaccurate CT images or are not clinically available, thus not widely implemented. The goal of this work is to use …
