A method of identifying a location of a region of interest within a breast utilizes compressed location coordinates for the region of interest recorded while the breast is under compression during an x-ray imaging procedure such as mammography or tomosynthesis. The compressed location coordinates are converted to uncompressed location coordinates using a mathematical tissue deformation model. The volume and density of the breast affects how the coordinates are translated for use with an ultrasound imaging system. A system including a computing system in communication with an ultrasound imaging system is utilized to perform the method. The resultant predicted location coordinates of the region of interest are used to guide a healthcare provider to potential lesions that are to be examined using ultrasound, where the potential lesions had been previously identified during a screening mammogram.
