摘要： A visualization system, an apparatus, and a visualization method are provided. The visualization system includes a laparoscope, a camera operatively coupled to the laparoscope, a light source operatively coupled to an illumination port of the laparoscope, and processing circuitry. The light source is configured to output one or more light beams each at a predetermined frequency to illuminate a target area. The processing circuitry is configured to process imaging data from the laparoscope received by the camera to generate one or more images of the target area including at least one laser speckle contrast image. The laparoscope is configured to output the one or more light beams toward the target area at a distal end thereof and to collect reflected and/or scattered light from the target area via the distal end.
