More Information
Summary:A method for correcting a volumetric image to address error due to deflection of a patient support is provided. The method includes obtaining a first set of projection data and a second set of projection data. The first and second sets of projection data are generated when the patient is at a first position and a second position, respectively, and are usable to reconstruct a first volumetric image and a second volumetric image, respectively. A corrected volumetric image is then determined based on the first and second sets of projection data.
