A CT scanner which provides an image of the area, the X-ray cone beam at least 1, X for generating a signal Ozuru the linear attenuation of the X-rays passing through the region from the X-ray source including at least one irradiating X-ray region a controller for controlling the X-ray cone beam one can receive signals, images from (a) at least data to obtain a plurality of rows and the line detector, the line attenuation data for the region on viewing angle different areas determining low spatial frequency components, and generates a spatial image of the first region (b) to the low-frequency component, determines the high spatial frequency component of the image (c) to the data, in the area (d) to the high frequency component CT scanner and a processor for combining the first image and the second image 1 so as to generate a spatial image of the second, to produce (e) CT images is disclosed.
