Abstract: Embodiments include a device, comprising: a mounting structure configured to mount the device to an external component; first circuitry; and anti-tamper circuitry electrically connected to the first circuitry and configured to disable at least one function of the first circuitry when the device is removed from the external component and methods of operating the device.

Abstract: Technology is described for electronically aligning a central ray of an x-ray tube to a radiation detector. In an example, an x-ray system includes an x-ray tube and a tube control unit (TCU). The x-ray tube includes a cathode that includes an electron emitter configured to emit an electron beam, an anode configured to receive the electron beam and generate x-rays with a central ray from electrons of the electron beam colliding on a focal spot of the anode, and a steering magnetic multipole between the cathode and the anode that is configured to produce a steering magnetic field from a steering signal. At least two poles of the steering magnetic multipole are on opposite sides of the electron beam. The TCU includes at least one steering driver configured to generate the steering signal. The TCU is configured to convert an offset value to the steering signal.

Abstract: Technology is described for calibrating a deflected position of a central ray of an x-ray tube to a radiation imager. An x-ray system includes an x-ray tube and a tube control unit (TCU). The x-ray tube includes a cathode that includes an electron emitter configured to emit an electron beam, an anode configured to receive the electron beam and generate x-rays with a central ray from electrons of the electron beam colliding on a focal spot of the anode, and a steering magnetic multipole between the cathode and the anode that is configured to produce a steering magnetic field from a steering signal. At least two poles of the steering magnetic multipole are on opposite sides of the electron beam. The TCU includes at least one steering driver configured to generate the steering signal. The TCU is configured to convert a position correction value to the steering signal.

Abstract: An X-ray tube may include a housing, a cathode, an anode, and a tube auxiliary unit or an authentication module. The cathode and the anode are positioned within the housing. The cathode and the anode are spaced apart such that a target surface of the anode is positioned to receive electrons emitted by the cathode. The tube auxiliary unit may be coupled to the housing. The tube auxiliary unit may include X-ray tube data including tube calibration data based on parameters of the X-ray tube. The authentication module may be configured to authenticate the X-ray tube with a tube control unit.
