Abstract
Systems and methods for visualizing scattered X-rays is provided for protecting medical staff during an examination with X-rays when an examination object is irradiated with X-rays emitted by an X-ray tube of an X-ray device. The method includes irradiating the examination object with the X-rays emitted by the X-ray tube, thereby producing scattered X-rays, ascertaining signals representing radiation from an initial radiation spectrum, wherein the radiation from an initial radiation spectrum has been produced by scintillation of the scattered X-rays in a gaseous scintillator in the form of nitrogen present in the ambient air, and outputting at least one image ascertained from the signals.

A method for visualizing scattered X-rays when an examination object is irradiated with X-rays emitted by an X-ray tube of an X-ray device, the method comprising:
- irradiating the examination object with the X-rays emitted by the X-ray tube, thereby producing scattered X-rays;
- ascertaining signals representing radiation from an initial radiation spectrum, wherein the radiation from an initial radiation spectrum has been produced by scintillation of the scattered X-rays in a gaseous scintillator in a form of nitrogen present in ambient air;
- and
- outputting at least one image ascertained from the signals.
A medical system for visualizing scattered X-rays, the medical system comprising:
- an X-ray device including an X-ray tube configured to emit X-rays to irradiate an examination object,
- a receiving unit configured for ascertaining signals representing radiation from an initial radiation spectrum, wherein the radiation from an initial radiation spectrum is produced by scintillation of the scattered X-rays in a gaseous scintillator in a form of nitrogen present in ambient air, and
- an output unit for outputting at least one image ascertained from the signals.
