Patent Images

1. An imaging device, comprising:

  • a substrate having a first side and a second side, the substrate configured to be affixed to a subject in an orientation where the first side faces towards a region of interest on a subject and the second side faces away from the region of interest on the subject;

    a plurality of light sources attached to the substrate, the plurality of light sources oriented to emit light away from the first side of the substrate;

    an optical detector attached to the substrate, the optical detector oriented to detect light incident on the first side of the substrate;

    one or more processing units in electronic communication with the plurality of light sources and optical detector;

    a communication module in electronic communication with the one or more processing units; and

    memory in electronic communication with the one or more processing units or within the one or more processor units, the memory storing one or more protocols executable by the one or more processing unit, the one or more protocols including instructions for;

    turning on and off respective light sources in the plurality of light sources;

    acquiring a plurality of images of the region of interest of the subject, wherein each image in the plurality of images is acquired at a different spectral band in a plurality of spectral bands;

    determining a tissue oxygenation parameter based on the plurality of images of the skin of the subject; and

    communicating an indication of the tissue oxygenation parameter to an output element via the communication module.
