A method and system of aligning plurality of physically scaled mammography images within at least one viewport comprising: categorizing each mammography image to a corresponding mammography view； determining the image dimensions of each image based on the pixel spacing； choosing a first mammography image for each mammographic view based on the image dimensions； centering the first mammography image of each mammographic view within the at least one viewport； generating a virtual line across the at least one viewport along a boundary of the first mammography image； and aligning subsequent mammography images of the same mammographic view such that a boundary of the mammography image is aligned to the virtual line.
