ABSTRACT:
A CT scanning method capable of increased resolution. An object to be scanned is positioned within a CT scanner, and the scanner is operated to perform a first scan to obtain a density value for each of a plurality of first pixels in a planar layer through the object. The scanner is then operated to perform a second scan to obtain a density value for each of a plurality of second pixels in the layer. The second pixels are different from the first pixels, and may be obtained by displacing the first pixels by a translation distance along a translation direction. For a given image element in the layer, a density value is then obtained by averaging the density values of the first and second pixels within which the image element is contained.
