  • Publication number: 20220108461
    Abstract: The present disclosure provides methods, systems, and devices for coregistering imaging data to form three-dimensional superimposed images of target such as 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 excise cancerous tissues, for example, breast tumors. Images can be in the form of videos.
