Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 6:
7. A non-transitory computer readable medium carrying instructions for controlling a processor to perform a method for compensating truncated MR images, the method including:
masking a volume of PET imaging data of a patient with a volume of truncated MR imaging data of a patient having a MR field of vision (FOV) that is smaller than the PET imaging volume to generate a masked PET image that includes one or more truncated regions of interest (ROIs) that are outside of the MR FOV:
identifying the one or more truncated ROIs in the masked PET image from the masking of the volume of the PET imaging data with the volume of the MR imaging data;
classifying the one or more truncated ROIs as types of anatomical structures that are outside the MR FOV, the structure of each truncated ROI including a thickness, shape, and size of the corresponding truncated ROI;
classifying an orientation of each classified anatomical structure as an up or down or side orientation; and
comp ensating for truncation in the truncated ROI s using a classification specific trtmcation compensation for each trtmcned ROI based on the classified anatomical structure in the masked PET image that is outside the MR FOV to generate compensated ROIs using anatomical image models of the classified anatomical structures that are oriented to match the respective classified up or down or side orientations.
