Effective dose and image quality for intraoperative imaging with a cone-beam CT and a mobile multi-slice CT in spinal surgery: A phantom study
The evolution of minimally invasive surgical techniques has increased the role of intraoperative imaging in spinal surgery. In the particular case of placements of pedicle screws in the lumbar spine, intraoperative-CT (i-CT) scans are required for navigation during surgery in three –dimensions (3D) and for the assessment of the accurate position of the titanium screw inside the cortical wall of the pedicles. Indeed, studies on navigation techniques coupled with 3D imaging have shown an increased accuracy of pedicle screw placement and patient safety compared to freehand or c onventional techniques [1–4].
