Abstract
The invention relates to a diaphragm unit 4 or a diaphragm unit 4 and an associated x-ray emitter 1 with adjustment option for displaying an asymmetrical area under examination, with the diaphragm unit 4 being able to be tilted in accordance with the invention relative to the x-ray emitter 1, preferably by moving it on a rail system 12 attached isocentrically to the tube focus 9 on the tube housing 2 and/or the unit 1;4 made up of diaphragm unit 4 and x-ray emitter 1 being able to be tilted isocentrically to the tube focus 9 of the x-ray tube 2.
Claims12
A diaphragm unit for use in an x-ray device of the type having an x-ray emitter positioned in a housing, comprising an assembly unit allowing for rotational movement of the diaphragm unit about the housing, so that the assembly unit isocentrically translates the diaphragm unit in its entirety about a source point of the x-ray emitter, allowing an asymmetrical part of an examination area to be irradiated by the x-ray emitter using the diaphragm unit.
An x-ray device, comprising:
- an x-ray emitter;
- and
- a diaphragm unit arranged on an assembly unit and facing the x-ray emitter for fading in an examination area, wherein the assembly unit is configured to isocentrically rotate the diaphragm unit about the x-ray emitter so that an asymmetrical examination area is irradiated by the x-ray emitter.
A method of adjusting a diaphragm unit of the type which receives radiation from an x-ray emitter in order to effect fading in an examination area to be irradiated by the x-ray emitter, the method including the steps of:
- connecting an assembly unit to provide a rotational path about a source point of the emitter;
- and
- connecting the diaphragm unit to the assembly unit for movement along the rotational path and about the x-ray emitter so that an asymmetrical part of the examination area is exposed to the radiation by moving the diaphragm unit.
