A large field of view projection image is obtained and a small field of view projection image is obtained. The two images are normalized, to take into account the difference between the count data between the images, and the way the images represent data. The large field of view image does not include truncation errors that are present in the small field of view image and therefore is stitched together with the smaller field of view image to use the improved data within the small field of view image with the truncation reduction enabled by the larger field of view image.
