    Intraoperative breast cancer margin detection via polarization-sensitive optical coherence tomography

    Current standard-of-care for breast conserving surgery (BCS) procedures relies on post-operative histopathology to provide a microscopic view and assessment of surgical margins. To avoid high reoperation rates there has been a great interest in developing new imaging solutions to visualize tissue intraoperatively, and provide real-time feedback on the margin status. Optical coherence tomography (OCT) is a high-resolution label-free, imaging technology that is the optical analogue to ultrasound imaging, except images are based on backscattered near-infrared light. Fundamentally, the contrast mechanism of OCT relies on the light scattering properties associated with different tissue structures. Unlike normal tissue with well-organized tissue structure ...
