SOFTWARE FOR USING MAGNETIC RESONANCE IMAGES TO GENERATE A SYNTHETIC COMPUTED TOMOGRAPHY IMAGE

摘要

A computing device may assign voxels of at least one magnetic resonance image to tissue region types from a set of region types; and optimize voxel intensity value weights for each of the region types to minimize a difference between (i) actual voxel intensity values of the planning computed tomography image and (ii) synthetic computed tomography voxel values determined by weighting the voxels of the region types of the at least one magnetic resonance image according to the voxel intensity value weights of the corresponding region types. The device may also assign voxels of magnetic resonance images of a treatment area of a patient to tissue region types from a set of region types; and generate a synthetic computed tomography image of the treatment area of the patient according to the magnetic resonance images and optimized voxel intensity value weights for each of the tissue region types.
