ABSTRACT:
An X-ray CT scanning apparatus comprises an X-ray source for irradiating a beam of X-ray to an object to be examined, a detector provided with at least two rows of detector elements for detecting the X-ray beam to have a real data, and a couch driver for traveling in an axial direction of the body of the object a couch on which the object is placed, in which the X-ray beam being irradiated from the X-ray source which is being rotated and simultaneously, the couch being traveled with the couch driver, the object is scanned in a helical direction so that the real data sampled by the detector is not identical in the sweep pattern to its opposite data. Two data located on both sides of the target slicing location may be selected from groups of the real data and their opposite data sampled by the detector and used to interpolate a data at the target slicing location. The group of the real data and their opposite data sampled by the detector may be filtered in the direction of slices to produce a desired data at the target slicing location. Also, a combination of the above three methods can be implemented.
