Abstract
Abstract An x-ray apparatus has a portable radiation detector having a housing containing a radiation transducer formed of individual detector cells that convert incident radiation, particularly x-radiation, into electrical signals. The radiation detector is implemented cable-free. A wireless transceiver for the infeed of operating energy and for the outfeed of the signals is provided. An advantage of this radiation detector is the cable-free construction, and the simple manipulation and reusability resulting therefrom. Moreover, the radiation detector is better suited to hygienic demands.
