Optical Coherence Tomography Guided Laser Cochleostomy: Towards the Accuracy on Tens of Micrometer Scale
Figure 7
(a) Erroneously applied laser pulse (black) due to tiny relative displacement between target area and laser optics and the originally planned pulse position (red); (b) illustration of a typical setup using conventional tracking system; ((c)-(d)) OCT as highly accurate optical tracking system: (c) artificial landmarks surrounding the cochleostomy and (d) the corresponding top view in three-dimensional OCT scan, bar = 250 μm [19].
