Image guidance can result in improved surgical outcomes, shorter operating times as well as a reduced likelihood of requiring a follow-up surgery for various medical interventions. Many intraoperative imaging systems utilize 2D computer monitors, making it difficult to correlate the surgical landscape with the displayed functional information as well as potentially distracting the surgeon. To address this issue, a miniature, wearable Near Infrared (NIR) fluorescent imaging system entitled Stereoscopic Optical Imaging Goggle is developed. The system is made up of two imaging sensors affixed to a wearable stereoscopic display, providing the surgeon with functional data in 3 dimensions with depth perception. We have characterized the system’s optical properties and fluorescent detection limits. In addition, we have demonstrated the efficacy of the system during surgical studies in chicken. We have found that the system can resolve fluorescent structures down to 0.25mm. The system was successfully guided the excision of fluorescent tissue from a chicken. To the best of our knowledge, the Stereoscopic Optical Imaging Goggle is the first wearable wide-field fluorescence imaging system that offers stereoscopic imaging capability and 3D depth perception.
