  • Cochlear shape description and analyzing via medial models 
    Gaa, Johannes; Kahrs, Lüder Alexander; Müller, Samuel; Majdani, Omid; Ortmaier, Tobias (Bellingham, Wash. : SPIE, 2015)
    Planning and analyzing of surgical interventions are often based on computer models derived from computed tomography images of the patient. In the field of cochlear implant insertion the modeling of several structures of ...
  • Methods for intraoperative, sterile pose-setting of patient-specific microstereotactic frames 
    Vollmann, Benjamin; Müller, Samuel; Kundrat, Dennis; Ortmaier, Tobias; Kahrs, Lüder Alexander (Bellingham, Wash. : SPIE, 2015)
    This work proposes new methods for a microstereotactic frame based on bone cement fixation. Microstereotactic frames are under investigation for minimal invasive temporal bone surgery, e.g. cochlear implantation, or for ...
  • Panorama imaging for image-to-physical registration of narrow drill holes inside spongy bones 
    Bergmeier, Jan; Fast, Jacob Friedemann; Ortmaier, Tobias; Kahrs, Lüder Alexander (Bellingham, Wash. : SPIE, 2017)
    Image-to-physical registration based on volumetric data like computed tomography on the one side and intraoperative endoscopic images on the other side is an important method for various surgical applications. In this ...
  • Percutaneous inner-ear access via an image-guided industrial robot system 
    Baron, S.; Eilers, H.; Munske, B.; Toennies, J.L.; Balachandran, R.; Labadie, R.F.; Ortmaier, T.; Webster, R.J. (London : SAGE Publications Ltd., 2010)
    Image-guided robots have been widely used for bone shaping and percutaneous access to interventional sites. However, due to high-accuracy requirements and proximity to sensitive nerves and brain tissues, the adoption of ...
  • Signal processing strategies for cochlear implants using current steering 
    Nogueira, Waldo; Litvak, Leonid; Edler, Bernd; Ostermann, Jörn; Büchner, Andreas (Heidelberg : Springer Verlag, 2009)
    In contemporary cochlear implant systems, the audio signal is decomposed into different frequency bands, each assigned to one electrode. Thus, pitch perception is limited by the number of physical electrodes implanted into ...
  • Toward automated cochlear implant insertion using tubular manipulators 
    Granna, Josephine; Rau, Thomas S.; Nguyen, Thien-Dang; Lenarz, Thomas; Majdani, Omid; Burgner-Kahrs, Jessica (Bellingham, Wash. : SPIE, 2016)
    During manual cochlear implant electrode insertion the surgeon is at risk to damage the intracochlear fine-structure, as the electrode array is inserted through a small opening in the cochlea blindly with little force-feedback. ...
