Patent ID: 8238649

Claim:
A method of displaying image data, the method comprising: obtaining projection data of an object using an x-ray imaging device by exposing an object to radiation at a plurality of view angles and detecting at least some of the radiation exiting the object to form the projection data; operating a computer to reconstruct the projection data at a reconstruction resolution to form image data comprising a plurality of voxels representing locations within the object, each of the plurality of voxels being assigned an associated intensity indicative of a density of the subject matter at the respective location, the reconstruction resolution defining the resolution of the image data for at least one dimension; determining a maximum resolution, for the at least one dimension above which variation in intensity between adjacent voxels in the at least one dimension is not supported by information in the projection data, the maximum resolution for the at least one dimension being determined based, at least in part, on at least one of geometry of the x-ray imaging device, a number of the plurality of view angles from which the projection data was obtained, a distribution of the plurality of view angles from which the projection data was obtained, and one or more radiation parameters of the radiation emitted from the x-ray imaging device; and displaying the image data, wherein the image data along the at least one dimension is displayed at or below the maximum resolution.
