Optical coherence tomography as a tracking device for OCT guided laser cochleostomy: algorithm and first results
2012
CURAC Jahrestagung
Preserved Fulltext
This is insufficient for an optical coherence tomography (OCT) guided laser cochleostomy which requires a much higher accuracy. ...
In this paper, we evaluate the use of OCT itself as a tracking device by locating artificial landmarks generated around the cochleostomy. ...
