Power delivery of an image modality system for transferring power from a transmission unit (e.g., stationary unit) to a reception unit (e.g., a moving and/or rotating unit). A modulated electric signal comprising at least two modulated characteristics (e.g., such as amplitude and frequency) is configured to (e.g., concurrently) supply power to both high voltage and lower voltage components () of the reception unit. An auxiliary component () is configured to utilize a first of the modulated characteristics (e.g., amplitude) to adjust/regulate a voltage applied to the lower voltage component (s), and a filter component () (e.g., such as a frequency selective circuit) is configured to utilize a second of the modulated characteristics (e.g., frequency) to adjust/regulate a voltage applied to the high voltage component (s).

Power delivery to a moving unit

One or more systems and/or techniques are provided for electrically coupling and/or decoupling a capacitive snubber component to/from an inverter as a function of a current in the inverter. A current sensing component may be configured to measure the current in the inverter and/or determine whether the current in the inverter exceeds a desired threshold. The desired threshold may be set at a value sufficient to reset the capacitive snubber component. When the current in the inverter is above the desired threshold, the capacitive snubber component may be coupled to the inverter. When the current in the inverter is below the desired threshold, the capacitive snubber component may be decoupled from the inverter. In this way, little to no energy stored in the capacitive snubber component may be dissipated in the inverter when the current in the inverter drops below a level sufficient to reset the capacitive snubber component.

Controlling capacitive snubber as function of current in inverter

Among other things, one or more techniques and/or systems for selectively inhibiting radiation from being generated by a radiation source are provided. A radiation source comprises an electrically conductive gate situated between a cathode and an anode. When a voltage potential is created between the gate and the cathode, a flow of electrons between the cathode and the anode is mitigated, thus inhibiting radiation from being generated by the radiation source. When the voltage potential is removed or lessened, electrons may more freely flow between the cathode and the anode to generate radiation. In some embodiments, a calibration, such as a dark calibration, may be performed while the gate mitigates the flow of electrons. Moreover, in some embodiments, an accelerating voltage applied to the radiation source may be held substantially constant when radiation is generated as well as when radiation generation is inhibited.

Dynamic control of radiation emission

Among other things, one or more techniques and/or systems are provided for varying a voltage applied to a radiation source of an imaging modality to vary an energy of emitted radiation. A power supply comprises at least two rectifiers, with a first rectifier being electrically separated from a second rectifier via a switching component. When the switching component is opened, the first and second rectifiers are effectively arranged in parallel, and when the switching component is closed, the first and second rectifiers are effectively arranged in series. The voltage applied by the power supply may be different based upon whether the rectifiers are arranged in parallel or in series, but the power output by the power supply may remain substantially constant regardless of the rectifier arrangement.
