1. A method for motion correcting molecular breast imaging (MBI) images, said method comprising: obtaining a plurality of two-dimensional (2D) images of a breast using a MBI system; selecting a reference image from the plurality of 2D images; selecting a feature of interest in the reference image; determining a location of the feature of interest in the reference image; calculating a correction value for each of a plurality of non-reference images based on a difference in the location of the feature of interest in the reference image and a location of the feature of interest in each of the non-reference images; and combining the non-reference images with the reference image based on the calculated correction values.
