摘要： A motion-enable device includes a mechanical switch and a capacitive sensor with a sensing region that is located adjacent to the mechanical switch. The mechanical switch enables a first signal when closed or actuated that indicates that the mechanical switch is in an active state. The capacitive sensor enables a second signal when a conductive object is disposed in the sensing region, where the second signal indicates that the capacitive sensor is in an active state. Enablement of operation of an apparatus depends on receipt of both the first signal and the second signal. The mechanical switch and the capacitive sensor act as the two separate switches required by functional safety requirements for a motion enable device. Because the sensing region of the capacitive sensor is adjacent to the mechanical switch, the first and second signals are generated when an operator actuates the mechanical switch with a single digit.

摘要： An imaging system (202) includes an X-ray radiation source (210) configured to emit radiation that traverses an examination region. The imaging system further includes a controller (220). The controller is configured to control an X-ray tube peak voltage of the X-ray radiation source to switch between at least two different X-ray tube peak voltages during a kVp switched spectral scan. The controller is further configured to control a grid voltage of the X-ray radiation source to follow the X-ray tube peak voltage during the spectral scan. The controller adjusts the grid voltage based on a predetermined mapping between a currently applied X-ray tube peak voltage and a corresponding grid voltage for a given focal spot size, thereby maintaining the given focal spot size throughout the spectral scan.

摘要： A system can have an x-ray source that generates a series of individual x-ray pulses for multi-energy imaging. A first x-ray pulse can have a first energy level and a subsequent second x-ray pulse in the series can have a second energy level different from the first energy level. An x-ray imager can receive the x-rays from the x-ray source and can detect the received x-rays for image generation. A generator interface box (GIB) controls the x-ray source to provide the series of individual x-ray pulses and synchronizes detection by the x-ray imager with generation of the individual x-ray pulses. The GIB can control x-ray pulse generation and synchronization to optimize image generation while minimizing unnecessary x-ray irradiation.

摘要： An x-ray tube having at least one focusing cup and an anode. The x-ray tube may have a first filament positioned in a first location between the focusing cup and the anode, the first filament having a first size, and a second filament positioned in a second location between the focusing cup and anode, the second filament having a second size that is substantially the same as the first size. The x-ray tube may also include a switching mechanism configured to engage the second filament upon failure of the first filament.

摘要： The present invention relates to an apparatus for generating X-rays. It is described to produce (210) with a power supply (40) at least two voltages between at least one cathode (20) and an anode (30), wherein the at least two voltages comprises a first voltage and a second voltage. The at least one cathode is positioned relative to the anode. Electrons are emitted (220) from the at least one cathode. Electrons emitted from the at least one cathode are interacted (230) with the anode with energies corresponding to the at least two voltages. X-rays are generated (230) from the anode, wherein the electrons interact with the anode to generate the X-rays. First X-rays are generated when the power supply produces the first voltage and second X-rays are generated when the power supply produces the second voltage. The power supply is controlled (250), such that a ratio between the first X-rays and the second X-rays is controllable.
