Claim One:
1. A method for identifying a lesion within a breast during an interventional magnetic resonance imaging (MRI)-guided breast biopsy procedure, the method comprising the steps of: acquiring one or more screening images of the breast that is uncompressed in a screening exam by an MRI; segmenting the lesion on the one or more screening images, creating a three-dimensional (3D) lesion mask of the segmented lesion on the screening images; acquiring one or more additional images of the breast that is compressed in an interventional MRI-guided breast biopsy procedure to produce interventional images, absent contrast enhancement; providing a computer processor for performing a non-rigid registration procedure between the uncompressed breast screening images from the screening exam and the compressed breast interventional images from the interventional MRI-guided breast biopsy procedure, wherein a transformation is produced to relate the one or more uncompressed breast screening images to the one or more compressed breast interventional images; wherein the step of performing non-rigid registration comprises (a) starting with a translation of the interventional images in order to overlap a field of view of the interventional images with a field of view of the screening images and (b) ending with the non-rigid registration procedure based on mutual information shared between the screening images and the interventional images; and displaying on a display unit the 3D lesion mask on the interventional images to a clinician to identify a target location of the lesion.
