Claim One:
1. A CT scanner for providing an image of a region comprising: at least one X-ray cone beam for illuminating the region with X-rays; a plurality of rows of X-ray detectors that generate signals responsive to line attenuation of X-rays from the at least one X-ray source that pass through the region; a controller that controls the at least one X-ray cone beam to acquire line attenuation data for the region for different view angles of the region; and a processor that receives the signals and: a) determines low spatial frequency components of the image from the data; b) generates a first spatial image of the region from the low frequency components; c) determines high spatial frequency components of the image from the data; d) generates a second spatial image of the region from the high frequency components; and e) combines the first and second images to generate the CT image.
