Automated method and system for the evaluation of disease and registration accuracy in the subtraction of temporally sequential medical images

摘要: An apparatus, method and computer program product for performing aided diagnosis on temporal subtraction images of objects. A mode a gray-level histogram is identified, threshold established at predefined fraction this modal value. All pixels with gray levels below that lie within the lung regions image remain “on,” while all other are set to zero. Area circularity requirements imposed eliminate false-positive regions. Areas pathologic change identified in manner may be presented as outlines or highlighted original radiographic so that, effect, becomes “background” process computer-aided diagnosis. The present invention also directed method, energy images, without subsequent diagnosis,
