Abstract: Medical interventions are often guided by opti-cal tracking systems and optical coherence tomography hasshown promising results for markerless tracking of soft tissue.The high spatial resolution and subsurface information con-tain valuable information about the underlying tissue structureand tracking of certain target structures is in principle possible.However, the small field-of-view complicates the selection ofsuitable regions-of-interest for tracking. Therefore, we extendan experimental setup and perform volumetric surface scan-ning of target structures to enlarge the field-of-view. We showthat the setup allows for data acquisition and that precise merg-ing of the volumes is possible with mean absolute errors from0.041 mmto0.097 mm.
