    Post mortem study of the intracochlear position of the nucleus standard 22 electrode array
    XU, JIN ; Dahm, M. C. ; Tykocinski, Michael. ; Shepherd, Robert K. ; Clark, Graeme M. ( 2000)
    The final position of an intracochlear cochlear implant electrode array can vary depending on the pathology, the insertion technique used and the type of electrode array used. The distance of the electrodes from the target neural elements and the presence of intracochlear fibrous tissue or new bone formation are believed to affect the performance of the device. A post mortem study was conducted to assess these factors.

    The role phase-contrast imagining in intra-cochlear electrode development
    Wilkins, S. ; Saudners, E. ; Clark, Graeme M. ; Cowan, R. ; XU, JIN ; Stevenson, A. W. ; Gao, D. ; Tykocinski, M. ; Cohen, L. ; Dahm, Markus ( 2000)
    In order to improve the design of intracochlear multichannel electrode arrays, it is fundamental that we have knowledge of the exact anatomical , position of the electrode within the scala of the cochlea. Currently, conventional skull radiography is still the mainstay of post-operative radiological assessment of electrode positioning. The present work investigates the use of phase-contrast radiography, a new x-ray modality, to provide improved imaging of the inner ear and the intracochlear electrode array in the human temporal bone (TB).
