Abstract:
1. A method of augmenting a tomographic projection image of a patient, the method comprising the steps of: obtaining a first sinogram data set from a patient; reconstructing the first sinogram data set into a first image; obtaining a second sinogram data set from the patient; reconstructing the second sinogram data set into a second image; aligning the first image to the second image to obtain an aligned image, so that optimal registration between the first and second image is obtained; reprojecting the aligned image into a reprojected sinogram data set; extracting data from the reprojected sinogram data set that is not available in the first sinogram data set; augmenting the first sinogram data set with the extracted data from the reprojected sinogram data set to obtain an augmented sinogram data set; and reconstructing the augmented sinogram data set into a third image.
