Title: SYNTHETIC COMPUTED TOMOGRAPHY IMAGING
Abstract:
The invention provides for a computer program product for calculating synthetic CT image (124). The computer program product comprises machine executable instructions (130) for execution by a processor (104). Execution of the machine executable instructions causes the processor to: receive (200) bone mineralization density data (114); receive (202) a magnetic resonance image (116) of a region of interest (309); calculate (204) an image segmentation (118) by segmenting the magnetic resonance image into a set of tissue types, wherein the set of tissue types comprises a cortical bone segmentation; calculate (206) a cortical bone Hounsfield value (120) using the bone mineralization density data; calculate (208) a Hounsfield unit mapping (122) by assigning at least one Hounsfield unit value to each of the set of tissue types in the image segmentation, wherein the cortical bone segmentation is assigned the cortical bone Hounsfield value; and calculate (210) the synthetic CT image using the Hounsfield unit mapping.
