Method and apparatus for power control in an image-based navigation system

摘要

An imaging system can include an imaging capturing portion, an image processing unit, a main power supply and a supplemental power supply. The image capturing portion can include a source that emits an emission signal towards a target to be imaged, and a receiver that receives the emission signal emitted by the source. The image processing unit can receive the received emission signal from the imaging capturing portion and generate image data based on the received emission signal. The main power supply can be coupled to the imaging capturing portion and the imaging processing unit for providing operational power thereto. The supplemental power supply can be coupled to the main power supply and the imaging processing unit. The supplemental power supply can be charged by the main power supply in a first mode and provide operational power to the imaging processing unit in a second mode.

主权项

1. An imaging system comprising:
a plurality of devices configured to capture an image of a patient, wherein the plurality of devices comprise
(i) a source that emits an emission signal towards the patient, and(ii) a receiver that receives the emission signal emitted by the source and generates an image signal; an image processing unit that receives the image signal from the receiver and generates image data; a main power supply; a supplemental power supply; and a power distribution module configured to (i) receive power from the main power supply and the supplemental power supply, (ii) during a first mode, control distribution of power from the main power supply to the source, the image processing unit, and the supplemental power supply, and (iii) during a second mode, control distribution of power from the main power supply and the supplemental power supply to the image processing unit, wherein the power distribution module does not supply power from the supplemental power supply to the image processing unit during the first mode, wherein the power distribution module is configured to, during the first mode, charge the supplemental power supply by supplying power from the main power supply to the supplemental power supply.
