The present disclosure relates to a method and system for adjusting a focal point position of an X-ray tube. The method may include: obtaining a first thermal capacity and a first position of a focal point of an X-ray tube; obtaining a second thermal capacity of the X-ray tube; determining a second position of the focal point the X-ray tube based on the second thermal capacity; determining a target grid voltage difference of a focusing cup of the X-ray tube based on the first position and the second position of the focal point; and adjusting the X-ray tube based on the target grid voltage difference.

The invention discloses X-ray machine ray tube heat dissipation device which comprises a heat dissipation pool and an X-ray machine ray tube arranged in the heat dissipation pool, wherein the heat dissipation pool is provided with a water inlet and a water outlet, and the water outlet of the heat dissipation pool is communicated with the water inlet of water tank.

The electron beam is typically dynamically steered after its generation on the path to the target. The steering is performed by one or more source coils. These coils produce the magnetic field outside the vacuum vessel allowing air/water/oil cooling to remove undesired heat. The magnetic field is then picked up inside the vacuum vessel with pole pieces and guided towards the region where the magnetic field is needed to steer the electron beam.

An x-ray source has a target assembly including a target, an electron source for generating electrons to impact the target, and a flight tube assembly separating the target assembly from the electron source and transporting a coolant to the target assembly. The flight tube assembly includes a flight tube interface ring, a target cartridge tube, and an electrical isolation ring between the flight tube interface ring and the target cartridge tube.

The disclosure relates, inter alia, to a rotary anode bearing assembly for an X-ray tube comprising at least one bearing outer ring and rolling elements arranged within the at least one bearing outer ring, which rolling elements roll on the at least one bearing outer ring and enclose a radially inner receiving space for receiving a rotor of an X-ray tube; comprising a bearing housing in which the at least one bearing outer ring is mounted, wherein the bearing housing circumferentially surrounds the at least one bearing outer ring.

The rotary anode bearing assembly according to the disclosure is characterized in that an end face of at least one bearing outer ring or of a caulking ring axially adjoining the bearing outer ring is caulked to an end face of the bearing housing by plastic deformation of material of the bearing housing and/or of the bearing outer ring and/or of the caulking ring.

An X-ray tube has a cathode housing having a radiation exit window, a cooled anode, a hot cathode, an insulation body, a supply line for coolant to the anode and a discharge line for coolant from the anode. The supply and discharge lines have a plurality of turns in the insulation body. The potted body has an inner and outer mold. The anode, the cathode housing and the potted body are fastened on the ceramic body. At least one plastic directing body aligns the hoses separated from the outer and inner mold. The potting space is filled with a plastic potting compound in a cured state so that the intermediate spaces between the turns on the one hand and the outer mold and the inner mold on the other hand are occupied by the plastic of the at least one directing body and/or the plastic of the potting compound.

According to one embodiment, an X-ray tube packing device packs an X-ray tube. The X-ray tube packing device includes an installation stand, an X-ray tube mounting portion to which the X-ray tube is mounted, and a rotation mechanism provided on the installation stand and that rotatably supports the X-ray tube mounting portion. The rotation mechanism changes the X-ray tube from a posture at the time of packing to a posture at the time of installation, which is different from the posture at the time of packing and is the posture at the time of placing the X-ray tube on the installation stand after unpacking.
