Abstract

An x-ray receiver for an x-ray apparatus is disclosed. In at least one embodiment, the x-ray receiver includes a detector holding apparatus designed such that it can be connected to a detector for receiving x-rays. The x-ray receiver also includes an x-ray grid, connected to the detector holding apparatus, for reducing scattered x-rays, which is designed and arranged to attenuate scattered x-rays with at least one predetermined directional component parallel to a detector plane. In at least one embodiment, the x-ray receiver includes at least one sensor for detecting x-rays that is designed and arranged to detect x-rays striking the detector and, as a function of the detected x-rays, to generate an irradiation signal that represents an x-ray dose or x-ray intensity of the detected x-rays.

at least one sensor to detect x-rays, the at least one sensor being designed and arranged to detect x-rays striking the detector and, as a function of the detected x-rays, to generate an irradiation signal that represents at least one of an x-ray dose and an x-ray intensity of the detected x-rays, wherein

the at least one sensor being designed to generate a distance signal representing a perpendicular alignment of the x-ray grid plane to an x-ray, the x-ray grid plane aligned relative to a predetermined position in the region of an x-ray transmitter.

2. The mobile x-ray receiver as claimed in claim 1, wherein the at least one sensor is arranged in a beam path, provided for receiving the x-rays via the detector, in such a way as to receive the x-rays before the x-rays strike the detector.

3. The mobile x-ray receiver as claimed in claim 1, wherein the at least one sensor is arranged in a beam path, provided to receive the x-rays via the detector, between the x-ray grid and the detector.

4. The mobile x-ray receiver as claimed in claim 1, wherein the at least one sensor is designed to detect the x-rays without substantially attenuating the x-rays.

5. The mobile x-ray receiver as claimed in claim 1, wherein the at least one sensor includes a sensor gas that is designed to generate at least partially free charge carriers upon detection of x-rays, and to generate the irradiation signal as a function of the free charge carriers.

6. The mobile x-ray receiver as claimed in claim 1, wherein the mobile x-ray receiver includes a detector with a multiplicity of detector matrix elements that are respectively designed to generate a detector signal as a function of received x-rays.

7. The mobile x-ray receiver as claimed in claim 6, wherein the detector matrix elements of the detector are arranged in detector rows and detector columns running transverse thereto, and the x-ray grid includes attenuation elements arranged in grid rows, the x-ray grid and the detector being arranged relative to one another in such a way that the grid rows of the x-ray grid run in a projection onto the detector plane with a transverse component relative to the detector rows and with a transverse component relative to the detector columns.
