Abstract
A method for correcting fat-induced aberrations in ultrasound imaging comprises segmenting a thermoacoustic absorption image of a region of interest into at least one fat region and at least one non-fat region, creating a speed of sound map by assigning a speed of sound to each region based on tissue type of the region, correcting aberrations in the segmented thermoacoustic absorption image using the assigned speeds of sound thereby generating a corrected thermoacoustic image, and correcting an ultrasound image of the region of interest using the corrected thermoacoustic image and the speed of sound map.
