OPTICAL COHERENCE TOMOGRAPHY SYSTEM AND METHOD FOR REAL-TIME SURGICAL GUIDANCE

摘要

An optical coherence tomography (OCT) system for real-time surgical guidance includes an optical source, an optical fiber configured to be optically coupled to the optical source, a plurality of OCT sensor heads configured to be optically coupled to the optical fiber, an optical detector configured to be optically coupled to the optical fiber, a signal processor configured to communicate with the optical detector to receive detected signals therefrom, and a display system configured to receive OCT image signals from the signal processor and to display an OCT image of at least a portion of a surgical region of interest in real time to provide surgical guidance. The plurality of OCT sensor heads includes a bulk sensor head configured to image at least a portion of the surgical region of interest from an external imaging position and an endoscopic sensor head configured to be inserted into the surgical region of interest to image at least a portion of the surgical region of interest from an internal imaging position. The bulk sensor head and the endoscopic sensor head are at least one of separate exchangeable sensor heads or a reconfigurable sensor head.
