ABSTRACT:
A system and method for automatic quantitative assessment of myocardial image quality includes a liver-heart artifact quantification unit for providing a sequence of images, detecting the heart position in each image, segmenting non-heart activity relative to the detected heart positions, measuring the liver-heart effect in each image based on the segmentations, fusing the measurements obtained in each image, and determining a quality number for the plurality of images responsive to the fused measurements; and also includes a heart detection unit for receiving the image sequence, generating a region of interest comprising the heart by 1-D pseudo-motion analysis of the image sequence, localizing the heart center by a training-based algorithm, fitting a curve to the localized heart centers of each image in the sequence, refining the heart center positions of localized heart centers falling outside of a tolerance distance from the fitted curve, and determining a bounding circle comprising the heart in accordance with the localized and refined heart center positions.
