A system and method for integrated image registration of cardiac magnetic resonance perfusion data are provided, where the system includes an estimation unit for estimating an edge parameter, a registration unit in signal communication with the estimation unit for registering the edge parameter in correspondence with a template-match between pixels in a first input image and pixels in a second input image, and a CPU in signal communication with said estimation unit and said registration unit for detecting a changed pixel location in accordance with said registration when the entropy of said second image is increased; and where the corresponding method for integrated image registration is of cardiac magnetic resonance perfusion data includes providing a contoured region of interest on a first image having a plurality of pixels, receiving a second image corresponding to a time other than that of said first image, calculating pixel intensities for the second image, estimating edge parameters for at least one of said first and second images, calculating a template-match between said first and second images, selecting a pair of pixel locations from at least one of said first and second images in accordance with said template-match, registering the estimated edge parameters in correspondence with said calculated template-match for a pair of pixel values at said selected locations in said first image and a pair of pixel values at said selected locations in said second image, and detecting a changed pixel location in accordance with said registration.
