Abstract:
1. A computer-implemented method of reconstructing an image object for a measured object in object space from image data in data space during a reconstruction process, the method comprising causing a computer to execute instructions for: providing zonal information separating the object space into at least two zones, the zonal information being derived from anatomical information of a CT or MR modality; providing at least two zonal image objects, each zonal image object being associated with one of the at least two zones and being from a functional imaging modality; reconstructing the image object using a data model derived from separately forward projecting the functional information from the functional imaging mode as each of the zonal image objects into data space, wherein the contribution of each zonal image object to the data model is weighted according to a zonal scaling factor, combining results of the separate forward projecting, and back-projecting the functional information of the image data from the combined results, the forward and back projecting of the functional information being without forward and back projecting of the anatomical information from the CT or MR modality; and outputting the image object, wherein the zonal information is used in combination with the functional information from the functional imaging modality in reconstructing the image object during the reconstruction process, wherein the zonal information is used to reconstruct the image object, wherein the image object is an integrated image comprising the functional and anatomical information.
