Semiautomatic Cochleostomy Target and Insertion Trajectory Planning for Minimally Invasive Cochlear Implantation

Figure 3

The distance between the approximated position of the basilar membrane (as computed with the landmark based approach) and its actual position in the corresponding micro-CT data (blue line) of 5 human cochleae is shown. An average error of 0.22 mm was observed in the region used for insertion trajectory computation (60^∘≥𝜃≥45^∘).
