Abstract: A method and apparatus are provided for reconstructing images from data obtained from scintillation events occurring within a projection space of a depth-of-interaction positron emission tomography system (10). The method includes the steps of identifying a segment of each depth-of-interaction detector (16) of respective pairs of depth-of-interaction detectors detecting the scintillation events of the data obtained within the projection space and estimating a set of sinograms from the data based upon a set of depth-independent point spread functions (40) of the identified segments of the respective pairs of depth-of-interaction detectors.

Abstract: A method and system for computerized registration of radionuclide images with radiographic images, including generating image data from radiographic and radionuclide images of the thorax (10, 12). Techniques include contouring the lung regions in each type of chest image (15, 16), scaling (17) and registration (19) of the contours based on location of lung apices, and superimposition (18) after appropriate shifting of the images. Specific applications are given for the automated registration of radionuclide lung scans with chest radiographs. The method in the example given yields a system that spatially registers and correlates digitized chest radiographs with V/Q scans in order to correlate V/Q functional information with the greater structural detail of chest radiographs.
