Developing 3D-Printed Synthetic Vertebrae with Realistic Surgical Haptic Feedback and Biomechanical Properties

Authors: Chloe Duncan, Andrew Kanawati, Peter Malek, Tess Reynolds

Affiliation: University of Sydney, Westmead Hospital, Image X Institute, Faculty of Medicine and Health, The University of Sydney

Abstract Preview: Purpose: Pedicle screw fixation, a standard spinal surgery procedure, has high misplacement rates (~40%) which decrease with surgeon experience. However, opportunities for surgical rehearsal, training...

Parameterized Dosimetric Models of the Lumbar Vertebrae for Patient-Informed Active Marrow Dosimetry in Radiopharmaceutical Therapy

Authors: Wesley E. Bolch, Chansoo Choi, Robert Joseph Dawson, Michael Lassmann, Maikol Salas-Ramirez, Bangho Shin, Johannes Tran-Gia, Yitian Wang

Affiliation: Department of Nuclear Medicine, University Hospital WΓΌrzburg, University of Florida

Abstract Preview: Purpose: Conduct a parameterized library of mesh-type skeletal models across the lumbar vertebrae. In radiopharmaceutical dosimetry, the hematopoietic active bone marrow is typically a dose-limiting n...

Twin Table-Tilt Imaging: Rapid Metal Artefact Reduction Intraoperative CBCT Imaging during Pedicle Screw Spinal Fixation

Authors: Owen Thomas Dillon, Andrew Kanawati, Tess Reynolds

Affiliation: Westmead Hospital, Image X Institute, Faculty of Medicine and Health, The University of Sydney

Abstract Preview: Purpose: Metal artefacts from implanted hardware and surgical tools remain a limitation for widespread adoption of intraoperative CBCT imaging. Gantry-based non-circular imaging trajectories have emer...
