Abstract
Methods and systems are provided for an adaptive state-of-charge for a portable imaging system. In one embodiment, a method comprises controlling an x-ray source to generate an x-ray exposure, measuring a voltage of a power supply coupled to the x-ray source during the x-ray exposure, and adjusting an available capacity of the power supply based on the voltage. In this way, the full capacity of a power supply may be utilized while compensating for aging of the power supply.

10. An imaging system, comprising:
-
a rechargeable power supply; an x-ray source electrically coupled to the rechargeable power supply; control circuitry for controlling the x-ray source; and a display configured to display a state-of-charge of the rechargeable power supply; wherein the control circuitry is configured with instructions in non-transitory memory that when executed cause the control circuitry to; measure a voltage of the rechargeable power supply while controlling the x-ray source during an x-ray exposure; adjust an available capacity of the rechargeable power supply based on the measured voltage; and update the state-of-charge based on the adjusted available capacity. - View Dependent Claims (11, 12, 13, 14, 15, 16)
