Radiation exposure during 3D fluoroscopy of the knee: an experimental study

Radiation exposure during 3D fluoroscopy of the knee decreases with increasing distance from the focus point. A higher number of scans in the high-resolution mode causes greater radiation exposure. In isocentric 3D fluoroscopy of the knee, a safe zone is located at least 1.5 m away from the focus point. T. Tharmviboonsri, K. Riansuwan, A. Nitising and B. Mahaisavariya.
