Clinical implementation of patient-specific quality assurance for synthetic computed tomography [PDF]
Physics and Imaging in Radiation OncologyBackground and purpose: In a magnetic resonance (MR) only planning workflow, MR image is the sole dataset acquired. In order to calculate the dose deposition, a synthetic CT (sCT) is generated to substitute the planning computed tomography (CT).
