Abstract: A system for outputting a representation of a wound in tissue comprises a housing configured to removably receive at least a portion of a wireless communication device. At least one light source coupled to the housing is configured to emit excitation light to illuminate a target which includes at least a portion of the wound. A power supply contained in the housing is configured to provide power to the light source. A non-transitory computer-readable medium stores a program executable to cause the performance of operations comprising detecting signals responsive to illumination of the target, outputting the representation of the target based thereon, storing data relative to one or more target surface parameter based on the detected signals, and displaying the representation. The signals correspond to at least one of endogenous or exogeneous fluorescence, absorbance, and reflectance from at least one biological component in and/or on the target.

Abstract: A system for acquiring data regarding a wound in tissue comprises at least one light source configured to directly illuminate a target surface with a homogeneous field of excitation light. An optical sensor is configured to detect signals responsive to illumination of an illuminated portion of a wound and the area around the wound. A thermal sensor is configured to detect thermal information regarding the illuminated portion of the wound and the area around the wound. A processor receives the detected signals and the detected thermal information and outputs data regarding the illuminated portion of the wound and the area around the wound. The output data may include wound size of the illuminated portion of the wound, bacterial load of the illuminated portion of the wound, or at least one temperature associated with the illuminated portion of the wound and the area around the wound. The data output by the processor may be displayed on a display of the system.
