Surface Scanning for Navigation Using High-Speed Optical Coherence Tomography

Abstract Medical interventions are often guided by optical tracking systems and coherence tomography has shown promising results for markerless of soft tissue. The high spatial resolution subsurface information contain valuable about the underlying tissue structure certain target structures is in principle possible. However, small field-of-view complicates selection suitable regions-of-interest tracking. Therefore, we extend an experimental setup perform volumetric surface scanning to enlarge field-of-view. We show that allows data acquisition precise merging volumes possible with mean absolute errors from 0.041mm 0.097mm.
