Abstract: There is provided a computer-implemented method of calculating an extended field of view (EFOV) from medical images, comprising: receiving multiple registered acquired medical images of a patient, the medical images having multiple imaging artifacts based on the medical imaging modality acquiring the medical images; analyzing the multiple medical images to identify locations of the multiple imaging artifacts within the medical images; calculating multiple multi-planar stitching surfaces such that seams connecting therebetween are outside the boundaries of the multiple imaging artifacts; and providing an extended field of view (EFOV) image having un-edited imaging artifacts from all stitched medical images.
