1. A mobile radiography system comprising:
- a moveable transport frame configured to travel across a floor;
an adjustable support structure coupled to the moveable transport frame;
an x-ray source coupled to the adjustable support structure;
a power transmitter to transmit wireless power signals; and
a first battery powered digital detector to capture a radiographic image generated by x-rays from the x-ray source, the digital detector comprising receiving circuitry configured to receive the wireless power signals to recharge the battery,wherein the first battery powered digital detector is configured to monitor a frequency of the transmitted wireless power signals, to not receive the transmitted wireless power signals, and to not recharge the battery only if the monitored frequency does not match a predetermined frequency range.

Abstract
A mobile radiography system has a moveable transport frame configured to travel across a floor. An adjustable support structure is coupled to the moveable transport frame and an x-ray source is coupled to the adjustable support structure. A power transmitter emits wireless power signals to a digital detector to charge a battery therein. Power signal receiving circuitry in the detector receives the wireless power signals to generate recharging current for the battery.
