A non-rotational CT system according to the present invention comprises: a plurality of X-ray generation units which are radially arranged by being spaced at certain intervals around an inspected object, and in which position correcting sensors are equipped on one side thereof a plurality of X-ray detection units which are arranged in separated spaces between the X-ray generation units, are provided alternately with the X-ray generation units, and in which position correcting sensors are equipped on one side thereof a control unit which receives signals from the position correcting sensors equipped in the X-ray generation units and the X-ray detection units, and adjusts the positions of each of the X-ray generation units and the X-ray detection units which face each other to precisely correspond with each other a data processing unit which stores two-dimensional X-ray images obtained from the X-ray detection units, and applies an image interpolation technique to calculate two-dimensional X-ray images between two directions and an image processing unit which converts data of the data processing unit into CT image data.
