Abstract
An x-ray acquisition apparatus has a spatially adjustable x-ray detector, a spatially adjustable x-ray source, and a control unit with which the x-ray source can be aligned relative to the x-ray detector. The control unit accounts for the position of radio-opaque objects in the examination room and, before an x-ray acquisition, outputs a signal is a radio-opaque object is located in the beam path of the x-ray source.
Claims13
An x-ray apparatus comprising:
- a spatially adjustable x-ray source that emits x-rays in a beam path;
- a spatially adjustable x-ray detector;
- and
- a control unit connected to said x-ray source and to said x-ray detector that aligns said x-ray source relative to said x-ray detector so that said x-ray detector is in said beam path to acquire diagnostic data from a subject between the x-ray source and the x-ray detector, said control unit identifying a position of a radio-opaque object in an examination room in which said x-ray source and said x-ray detector are located that blocks at least part of said beam path from reaching said x-ray detector that would otherwise be used to acquire diagnostic data from the subject and that, before acquiring diagnostic data from the subject with said x-ray source and said x-ray detector, emits a humanly perceptible signal if and when the radio-opaque object is located in the beam path.
