  • Surgical navigation technology based on augmented reality and integrated 3D Intraoperative Imaging a spine cadaveric feasibility and accuracy study
    Spine, 2016
    Co-Authors: Adrian Elmi-terander, Halldor Skulason, John Racadio, Drazenko Babic, Nijs Van Der Vaart, Michael Söderman, Reyn Homan, Rami Nachabe
    Abstract:

    STUDY DESIGN A cadaveric laboratory study. OBJECTIVE The aim of this study was to assess the feasibility and accuracy of thoracic pedicle screw placement using augmented reality surgical navigation (ARSN). SUMMARY OF BACKGROUND DATA Recent advances in spinal navigation have shown improved accuracy in lumbosacral pedicle screw placement but limited benefits in the thoracic spine. 3D Intraoperative Imaging and instrument navigation may allow improved accuracy in pedicle screw placement, without the use of x-ray fluoroscopy, and thus opens the route to image-guided minimally invasive therapy in the thoracic spine. METHODS ARSN encompasses a surgical table, a motorized flat detector C-arm with Intraoperative 2D/3D capabilities, integrated optical cameras for augmented reality navigation, and noninvasive patient motion tracking. Two neurosurgeons placed 94 pedicle screws in the thoracic spine of four cadavers using ARSN on one side of the spine (47 screws) and free-hand technique on the contralateral side. X-ray fluoroscopy was not used for either technique. Four independent reviewers assessed the postoperative scans, using the Gertzbein grading. Morphometric measurements of the pedicles axial and sagittal widths and angles, as well as the vertebrae axial and sagittal rotations were performed to identify risk factors for breaches. RESULTS ARSN was feasible and superior to free-hand technique with respect to overall accuracy (85% vs. 64%, P

  • Intraoperative Imaging modalities and compensation for brain shift in tumor resection surgery
    International Journal of Biomedical Imaging, 2017
    Co-Authors: Siming Bayer, Andreas Maier, Martin Ostermeier, Rebecca Fahrig
    Abstract:

    Intraoperative brain shift during neurosurgical procedures is a well-known phenomenon caused by gravity, tissue manipulation, tumor size, loss of cerebrospinal fluid (CSF), and use of medication. For the use of image-guided systems, this phenomenon greatly affects the accuracy of the guidance. During the last several decades, researchers have investigated how to overcome this problem. The purpose of this paper is to present a review of publications concerning different aspects of Intraoperative brain shift especially in a tumor resection surgery such as Intraoperative Imaging systems, quantification, measurement, modeling, and registration techniques. Clinical experience of using Intraoperative Imaging modalities, details about registration, and modeling methods in connection with brain shift in tumor resection surgery are the focuses of this review. In total, 126 papers regarding this topic are analyzed in a comprehensive summary and are categorized according to fourteen criteria. The result of the categorization is presented in an interactive web tool. The consequences from the categorization and trends in the future are discussed at the end of this work.
