Embodiment Construction

[0029] figure 1 An x-ray emitter system with an x-ray emitter 100 and, according to the invention, with a first cooling device 110 and a second cooling device 120 is shown. The X-ray emitter 100 includes a cathode 210 , a rotating anode 380 , an output window 360 and a deflection magnet system 230 . In the region of cathode 210 there are high demands on the electrical insulation properties, but this only accounts for a small part of the overall heat loss of x-ray emitter 100 . Most of the heat losses of x-ray emitter 100 occur in the region of rotating anode 380 and in the region of output window 360 , but especially in monopolar x-ray systems there are no requirements for high-voltage insulation.

[0030] The first cooling device 110 is designed as an active, closed cooling circuit. The cooled first coolant 330 flows into the first shell 300 from the intercooling system 400 or the heat exchanger through the coolant inlet 310 in the first shell 300 of the first cooling devic...

Abstract

The invention discloses a coolant cooled X-ray emitter system and a medical X-ray imaging system with an X-ray emitter (100) comprising a cathode (210), an anode (380) and an output window (360), wherein the first cooling device (110) outputs heat from the anode (380) and the output window (360), and the second cooling device (120) outputs heat from the cathode (210). An advantage of the invention is that the cooling of the x-ray emitter (100) is optimized, for which purpose coolants with high electrical insulating properties or high cooling properties can be used as required for the different regions of the x-ray emitter (100).

Description

technical field [0001] The invention relates to a coolant cooled X-ray emitter system and a medical X-ray imaging system comprising said X-ray emitter system with an X-ray emitter and two cooling loop loop. Background technique [0002] An X-ray emitter system usually consists of an X-ray emitter and a cooling device connected to the X-ray emitter. The x-ray emitter usually consists of an evacuated x-ray tube and an x-ray emitter housing surrounding the x-ray tube. [0003] In order to operate an x-ray emitter, high voltage must be supplied to the x-ray tube. The high-voltage feed starts from the connection of the emitter housing through the interior to the contacts provided for this purpose of the X-ray tube, which must meet the corresponding electrical insulation requirements, because the emitter housing is usually at ground potential (Massepotenzial) . [0004] During the operation of the x-ray tube, heat is generated at various points of the x-ray tube, which in tota...
