  • Patent number: 10656101
    Abstract: An X-ray imaging device includes a color sensor configured to generate a color signal indicating a particular color sensed, an imaging matrix of pixel detector elements that are each configured to detect photon energy and generate an image signal, and a controller that is coupled to the color sensor, the imaging matrix, and the wireless transceiver. The controller is configured to receive a color signal from the color sensor, determine an identifier of the computing device external to the X-ray imaging device based on the color signal, and change at least one operational setting of the X-ray imaging device based on the identifier.
