Detailed Description
Fig. 1 shows a cross section of a conventional X-ray radiator 10 according to the prior art. The conventional X-ray radiator has a first housing part 11 and a second housing part 12. The first housing part 11 and the second housing part 12 are connected to each other by means of a screw connection 13. The sealing element is arranged between the first housing part 11 and the second housing part 12.
Fig. 2 shows a partial cross section of the X-ray radiator 20. The X-ray radiator 20 has an X-ray radiator housing, an X-ray tube and a cooling medium.
The X-ray tube can comprise a stationary anode, a rotating anode or a rotating piston. The X-ray radiator 20 is configured for medical imaging and/or material examination. The X-ray tube is configured to generate X-ray radiation. Electrons are accelerated from the cathode of the X-ray tube to the anode of the X-ray tube. When an electron impinges on the anode, X-ray radiation is typically generated.
The cooling medium cools the X-ray tube, in particular the anode of the X-ray tube. The cooling medium comprises a gas and/or a liquid.
The high-voltage unit for supplying the X-ray tube can be arranged within the X-ray emitter housing or outside the X-ray emitter housing. The X-ray emitter housing typically comprises metal and/or plastic. The X-ray tube and the cooling medium are disposed within the X-ray emitter housing.
The X-ray emitter housing has a cylindrical housing part 21, a cover 22 for the cylindrical housing part 21 and at least one bayonet closure. The cylindrical housing portion 21 can be barrel-shaped. In principle, it is conceivable for the cylindrical housing part 21 to have a further cover on the side of the X-ray emitter housing opposite the cover 22. A cover 22 closes the cylindrical housing part 21 on the upper side and another cover closes the cylindrical housing part 21 on the lower side. The further cover can be releasably connected to the cylindrical housing part 21, for example by means of at least one further bayonet closure, or alternatively fixedly connected thereto, in particular by means of screws and/or welds.
The cover 22 and/or the further cover closes the cylindrical housing part 21 by means of at least one bayonet closure, so that the X-ray radiator housing is hermetically sealed. In this case, it is preferable that the cooling medium cannot overflow at the interface between the cover 22 and the cylindrical housing portion 21. In order to mount the X-ray tube in the cylindrical housing portion 21, the cover 22 can preferably be released.
This embodiment shows an X-ray radiator 20 with a closed X-ray radiator housing. In this case, the cover 22 is preferably connected to the cylindrical housing part 21 in a form-fitting manner.
In this embodiment, at least one mortise slot 23 of the bayonet closure is provided on the cylindrical housing part 21. At least one bayonet closure tenon 24 is provided on the cover 22. In an alternative embodiment, the tongue of the at least one bayonet closure is arranged on the cylindrical housing part 21 and the tongue-and-groove of the at least one bayonet closure is arranged on the cover 22.
In a particularly preferred embodiment, the X-ray emitter housing has three bayonet closures which are arranged radially offset. The three bayonet closures are preferably spaced apart at the same angle, for example at 120 °. It is conceivable for the X-ray emitter housing to have more than three bayonet closures, for example distributed over the cover 22 and the further cover.
The X-ray emitter housing has an annular sealing element 25. The annular sealing element 25 can be of circular, oval or angular design in cross section. An annular sealing element 25 is provided on the cover 22 in this embodiment in the manner: the cover 22 has a preferably annular recess for receiving an annular sealing element 25. The annular sealing element 25 can be an O-ring.
In a preferred embodiment, the sealing element 25 has a wire diameter which is greater than the spacing between the cover 22 and the cylindrical housing part 21 of the closed X-ray emitter housing. In this case, the sealing element can reduce, preferably eliminate, the gap in the connection between the cylindrical housing part 21 and the cover 22. The distance is in particular dependent on the depth of the annular recess for receiving the annular sealing element 25.
Fig. 3 shows the X-ray emitter 20 in a partially open first perspective view of the X-ray emitter housing. Fig. 3 and 4 show, instead of the annular sealing element, an annular recess for receiving the annular sealing element 25.
Fig. 4 shows the X-ray emitter 20 in a second perspective view, partially, with the X-ray emitter housing not closed.
Fig. 5 shows the X-ray emitter 20 with the fastening device 26 partially with the X-ray emitter housing closed. The X-ray emitter housing has a fastening element 26, which fastens the closed X-ray emitter housing during operation of the X-ray emitter 20. The fixing element can be a fixing pin or a fixing peg.
Although the details of the invention have been described and illustrated in the context of preferred embodiments, the invention is not limited by the examples disclosed, and other variants can be derived therefrom by those skilled in the art without departing from the scope of the invention.
