Generation of Pseudo-CT using Two Sets of MRI Scans for MRI-only Radiation Therapy

WWith increasing interests in magnetic resonance imaging (MRI)-only radiation therapy (RT) and the emergence of MRI system integrated with the linear accelerator, a method substituting the computed tomography (CT) in radiation therapy is required. The method to substitute the CT is by generating a pseudo-CT (pCT). A CT is necessary to provide the electron density information and to calculate the simulated dose distribution in treatment plans.
