ABSTRACT:
In computerized tomography apparatus having a radiation source and a detector, when the radiation source and the detector are rotated in a rotational direction, acquisition of computerized tomogram data takes place in accordance with a data acquiring direction. When the radiation source and the detector are rotated in a rotational direction opposite to the rotational direction, acquisition of the computerized tomogram data is also performed from a data acquiring direction opposite to the data acquisition direction, thereby agreeing with the position of imaginary source. The position of imaginary source is near a subject than that of the radiation source, so that a high resolution is obtained.
