Abstract:
1. A method of analyzing medical image data of a subject from an imaging modality using a tracer, comprising the steps of: supplying a computerized processor with image data obtained from detection of tracer emission events in a plurality of voxels of a scanned imaging volume; in said processor, automatically processing the image data to establish, for each of said voxels, sub-periods within a scan period for the emission events; in said processor, calculating a rate of change of emission events per unit time for such of said voxels; and in said processor, reconstructing a derivative image comprised of voxels each representing said calculated rate of change of emission events per unit of time for the respective voxels, and making said derivative image available in electronic form at an output of said processor in a format allowing said derivative image to be displayed.
