Towards Automated Ear Surgery: Improved Calibration and Registration ProceduresPublic
Downloadable Contentopen in viewer
A micro-electro-mechanical system (MEMS) based hydrophone inserted into the cochlea may be utilized to study acoustic pressure distribution. The objective of this project, performed through collaboration between WPI and UniversitätsSpital Zürich, was to develop an improved procedure for experiments at the UniversitätsSpital Zürich that would increase the insertion accuracy. This is necessary due to the small scale, complex anatomy, and delicate nature of the inner ear. This was done by calibrating tools and completing registration and insertion processes. The goal was to achieve an overall accuracy of 250 microns, which was met with a final accuracy below 200 microns, suggestive that the devised procedure can provide an accurate roadmap for future experiments.
