A surgical imaging system includes an endoscope, a processor, and a display. The endoscope includes an elongated shaft having a distal end portion, an imager attached to the distal end portion and configured to capture an image of tissue, an infrared transmitter attached to the distal end portion of the shaft for transmitting infrared light to tissue, and an infrared receiver attached to the distal end portion of the shaft for receiving infrared light reflected by the tissue. The processor is in communication with the infrared transmitter and the infrared receiver and is configured to identify generate a digital image of vasculature in the tissue based on data received from the infrared receiver. The display is configured to display the image of the tissue captured by the imager with the digital image of the vasculature overlaying the image of the tissue.
