Exclusion criteria

Exclusion criteria: Patients who lack the capacity to provide informed consent or to understand the nature of the study Surgeries in which the following devices are not available: - Cios Spin C-arm equipped with a reference array (Siemens) - PULSE platform with LessRay software (NuVasive) - Live dosimeter (RaySafe)

Design outcomes

Primary

MeasureTime frame
The primary endpoint is the individual radiation exposure of the operator during a single surgical procedure, measured in milligray (mGy). The measurement is performed continuously throughout each procedure and documented after its completion. Data are collected using a real-time dosimeter (RaySafe Live dosimeter), which is worn above the lead apron.

Secondary

MeasureTime frame
Radiation exposure of assistent and scrub nurse measured in mGy using real-time dosimetry Dose area product (mGycm²) Fluoroscopy time (s) Assessment of image quality in the two groups by independent observers Assessment of the position of the pedicle screws in postoperative CT by an independent observer
