Abstract
A surgical image acquisition system includes multiple illumination sources, each source emitting light at a specified wavelength, a light sensor to receive light reflected from a tissue sample illuminated by each of the illumination sources, and a computing system. The computer system may receive data from the light sensor when the tissue sample is illuminated by the illumination sources, determine a depth of a structure within the tissue sample, and calculate visualization data regarding the structure and its depth within the tissue. The visualization data may have a format for use by a display system. The structure may include vascular tissue. The illumination sources may include red, green, blue, infrared, ultraviolet, and white light sources. The structure depth may be determined by a spectroscopy method or a Doppler shift method. The system may include a controller and computer enabled instructions to accomplish the above.
