Abstract
A universal X-ray device has a movably suspended holder at which an X-ray radiator and a radiation detector are arranged, with the radiator being mounted so as to be pivotable around at least one axis perpendicular to the plane of the holder, and with the detector being displaceably mounted in the detector plane.
Claims14
A universal X-ray device comprising:
- an X-ray radiator;
- a radiation detector for detecting X-rays emitted by said radiator;
- a movably suspended holder having a holder plane;
- a radiator mount for mounting said radiator to said holder so that said radiator is rotatable around at least one axis perpendicular to said holder plane;
- and
- a detector mount for mounting said detector to said holder allowing displacement of said detector in said detector plane.

A universal X-ray device wherein said holder is a C-arm having a first end at which said radiator mount and said radiator are disposed, and a second end at which said detector mount and said detector are disposed.
A method for operating an X-ray device comprising the step of:
- providing a movably suspended holder having a holder plane;
- mounting an X-ray radiator to said holder so as to be rotatable around at least one axis perpendicular to said holder plane;
- mounting a radiation detector, for detecting radiation from said radiator, to said holder for displacement in said detector plane;
- moving said detector for obtaining a plurality of X-ray images using said radiator and said detector from a plurality of exposure positions on a circular arc around a focus of said radiator so that a central ray of an X-ray beam emitted from said radiator is perpendicularly incident on a middle of said detector;
- and
- combining images respectively obtained at said exposure positions to obtain a large-format composite X-ray image without distortion.
