Generative Adversarial Network, Metal Artifacts Reduction, Cochlea Implantation
We propose a 3D metal artifact reduction method using convolutional neural networks for post-operative cochlear implant imaging.
Metal artifacts simulation starts from a cochlea implantation fusion image and ends with the simulated post-operative image.(Fig. 15)

Approximate maximum likelihood, kinematic surface recognition, natural growth
To improve therapies for hearing loss and deafness, e.g., with auditory neuroprostheses, we developed a reliable detection algorithm for the cochlear modiolar axis in CT images (Fig. 16). The algorithm was tested in an experimental study with 4 experts in 23 human cochlea CT data sets  . Our experiments showed that the algorithm reduces the alignment error providing more reliable modiolar axis detection for clinical and research applications.
