    Abstract: The present disclosure provides methods, systems, and devices for coregistering imaging data to form three-dimensional superimposed images of a biological target such as a wound, a tumor, or a surgical bed. A three-dimensional map can be generated by projecting infrared radiation at a target area, receiving reflected infrared radiation, and measuring depth of the target area. A three-dimensional white light image can be created from a captured two-dimensional white light image and the three-dimensional map. A three-dimensional fluorescence image can be created from a captured two-dimensional fluorescence image and the three-dimensional map. The three-dimensional white light image and the three-dimensional fluorescence image can be aligned using one or more fiducial markers to form a three-dimensional superimposed image. The superimposed image can be used to track wound healing and to excise cancerous tissues, for example, breast tumors. Images can be in the form of videos.

    Abstract: A portable imaging system for visualizing bacteria in a wound in real time includes an excitation light source configured to emit violet and/or blue excitation light to illuminate a wound and cause at least one biomarker associated with the wound to fluoresce and a camera configured to detect fluorescence emitted by the at least one biomarker associated with the wound in response to illumination of the wound with the excitation light. A portable frame is configured to support the camera and the excitation light source for hands-free operation and to position the camera and the excitation light source relative to the wound. The system also includes a power source for the excitation light source.
