  • Patent number: 11937899
    Abstract: An imaging system includes an illuminator for providing illumination on a region of interest, one or more first detectors for detecting reflections of the illumination, and a processing unit. The processing unit is configured to: receive a first image containing the region of interest; determine a first region of high specular reflection in the first image based on the reflections of the illumination on the region of interest; mask the first image by substituting a default color designating masking to alert a user to incomplete image information in the first region of high specular reflection to create a masked first image; and generate a composite image based on the masked first image and a fluorescence image of the region of interest.
