Abstract
In order to achieve effective cooling, an X-ray emitter with a tube housing having a vacuum is provided. At least one anode is arranged in the tube housing, such that the anode is irradiated by an electron beam generated in a cathode and accelerated through an electrical field. The anode is excited, such that an X-ray deceleration radiation is emitted. The X-ray emitter has a thermoelectric converter (e.g., at least one thermophotovoltaic cell) for generating electrical energy. The thermoelectric converter is arranged, such that the thermoelectric converter may be irradiated at least in part by a heat radiation emanating from the anode.
Claims18
An X-ray emitter comprising:
- a tube housing having a vacuum, in which at least one anode is arranged, the at least one anode being irradiatable by an electron beam generated in a cathode and accelerated through an electrical field, and excited, such that an X-ray deceleration radiation is emitted;
- and
- a thermoelectric converter configured to generate electrical energy, the thermoelectric converter being arranged, such that the thermoelectric converter is irradiatable at least in part by a heat radiation emanating from the anode.
A medical mobile X-ray device comprising:
- an X-ray emitter comprising:
- a tube housing having a vacuum, in which at least one anode is arranged, the at least one anode being irradiatable by an electron beam generated in a cathode and accelerated through an electrical field, and excited, such that an X-ray deceleration radiation is emitted;
- and
- a thermoelectric converter configured to generate electrical energy, the thermoelectric converter being arranged, such that the thermoelectric converter is irradiatable at least in part by a heat radiation emanating from the anode;
- and
- an X-ray detector, in which the electrical energy generated usable to operate at least one component of the mobile X-ray device.
