Abstract

An X-ray computer tomography apparatus wherein a conical X-ray beam is radiated on a local area of an object while a rotary means with an X-ray generator and a two-dimensional X-ray image sensor faced to each other is rotated relative to the object which is disposed between the X-ray generator and the two-dimensional X-ray image sensor. The X-ray computer tomography apparatus comprises a preliminary imaging means for imaging the object under plural positional conditions wherein positional relations among the X-ray generator, the object and the two-dimensional X-ray image sensor are varied, a processing means for obtaining a three dimensional position of a target region of the object by calculating a two-dimensional positional data of a target region of the object which is determined on plural fluoroscopic images obtained by the preliminary imaging means, a position adjustment means for controlling the positional relation among the X-ray generator, the object and the two-dimensional X-ray image sensor in such a manner that the rotary center comes to the three dimensional position obtained by the processing means; and a main imaging means for obtaining a sectional image of the object while the rotary means and the object are relatively rotated after adjusting by the position adjustment means.
