Optical Coherence Tomography for Smart Laserosteotome

This project develops an Optical Coherence Tomography system that provide volumetric (3D) monitoring of the laser surgery process in real time. This monitoring will help the surgeon to specifically determine the cutting depth and how the cut being made in real time. In this way, it will provide high specificity in laser cutting which can prevent cutting important and critical tissues. This system also will monitor changes in bone and/or tissue properties. To develop this system, we will need to investigate how to characterize bone and tissue during laser cutting (e.g. optical, mechanical, thermal) by using Optical Coherence Tomography. We will design and build the OCT system and integrate it into an endoscopic/fiberscopic laser surgery system. (Arsham Hamidi and Yakub Bayhaqi)
