Interventional optical coherence tomography for surgical guidance

Optical coherence tomography (OCT) uses low-coherence interferometry to perform optical ranging measurements within biological tissue. Recent advances in OCT technology have permitted high-speed imaging at 4-8 frames/s. In vivo catheter/endoscope-based OCT imaging has recently been performed in a rabbit. OCT has also shown a feasibility for surgical diagnostics and for assessing microsurgical repairs of vessels and nerves. In this study, we investigate the use of high-speed OCT as an interventional imaging modality for surgical guidance. OCT can provide continuous image-guidance for the precise delivery of high-power laser radiation and selective ablation of diseased tissue.
