AUTOMATED METHOD AND SYSTEM FOR THE ALIGNMENT AND CORRELATION OF IMAGES FROM TWO DIFFERENT MODALITIES

摘要

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 registradon of radionuclide lumg 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.
