## Abstract

A surgical visualization system that can include a structured light emitter, a spectral light emitter, an image sensor, and a control circuit is disclosed herein. The structured light emitter can emit a structured pattern of electromagnetic radiation onto an anatomical structure. The spectral light emitter can emit electromagnetic radiation including a plurality of wavelengths. At least one of the wavelengths can penetrate a portion of the anatomical structure and reflect off a subject tissue. The image sensor can detect the structured pattern of electromagnetic radiation reflected off the anatomical structure and the at least one wavelength reflected off the subject tissue. The control circuit can receive signals from the image sensor, construct a model of the anatomical structure, detect a location of the subject tissue, and determine a margin about the subject tissue, based on at least one signal received from the image sensor.
