ABSTRACT:
A device for forming X-ray images, includes an X-ray source for generating an X-ray beam, a photoconductor for converting X-rays into a charge pattern, which photoconductor is provided on a rotationally symmetrically constructed rotatable carrier, a charging device for uniformly charging the surface of the rotating photoconductor prior to the X-ray exposure, a reading unit for converting the charge pattern on the surface of the rotating photoconductor into electric image values after an X-ray exposure, and a housing for the rotating parts which includes an area which is transparent to X-rays. The device enables X-ray images of a patient to be formed in at least one position other than the recumbent position in that the X-ray source can be positioned in different angular positions in an angular range about the axis of rotation, and that the area which is transparent to X-rays extends across such a part of the housing that the photoconductor can be exposed in any angular position of the X-ray source within the angular range.
