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.
Claims20
A method, comprising:
- 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.
1 more element
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.
7 more elements
A method, comprising:
- measuring a voltage of a rechargeable power supply coupled to an x-ray source during an x-ray exposure;
- reducing an available capacity of the rechargeable power supply based on the voltage;
- updating a state-of-charge of the rechargeable power supply based on the reduced available capacity;
- and
- displaying the updated state-of-charge of the rechargeable power supply.
