An X-ray apparatus for collecting X-ray transmission data of a subject from a plurality of directions to generate an X-ray transmission image or X-ray CT image of the subject, which includes an X-ray generator for generating an X-ray, an X-ray detector for detecting a transmission X-ray after the X-ray generated by the X-ray generator is transmitted through the subject, a rotation unit for rotating an imaging unit including the X-ray generator and the X-ray detector around the subject, a data collector for converting an output signal of the X-ray detector to a digital signal and collecting the digital signal, a signal processor for subjecting data collected by the data collector to a signal processing operation, a display for displaying thereon as an image the data collected by the data collector and the data subjected by the signal processor to the signal processing operation, and a position change unit for moving a relative position of a rotation center of the imaging unit and the subject in a direction parallel to a rotation plane of the rotation, and wherein the imaging unit is rotated by the rotator around the subject and at the same time the relative position is changed by the position change unit in a direction parallel to the rotation plane to perform X-ray fluoroscopic or radiographic operation or CT scan.
A fluoroscopic or radiographic method or CT scan method in which a pair of an X-ray source and an X-ray detector opposed to the X-ray source is rotated on a circular orbit and at the same time a subject is moved parallelly with respect to a rotation plane of said pair to perform X-ray fluoroscopic or radiographic operation or CT scan.
A fluoroscopic or radiographic method or CT scan method in which a pair of an X-ray source and an X-ray detector opposed to the X-ray source is rotated on a circular orbit and at the same time a subject is subjected to a composite movement corresponding to a combination of a periodical reciprocating movement on a straight line parallel to a rotation plane of said pair and a vertical movement with respect to said rotation plane to perform X-ray fluoroscopic or radiographic operation or CT scan.
An X-ray apparatus for collecting X-ray transmission data of a subject from a plurality of directions to generate an X-ray transmission image or X-ray CT image of said subject, comprising:
