Implication

Experimental evaluation demonstrates enhanced image quality and reduced radiation dose during spine surgery, suggesting mobile cone-beam CT improves real-time surgical precision.

Key Points

To evaluate image quality, radiation dose optimization, and interventional guidance integration of a high-performance mobile C-arm cone-beam CT prototype for spine surgery.
Evaluated a high-performance mobile C-arm prototype capable of intraoperative cone-beam CT (CBCT) acquisition.
Developed task-specific protocols to balance radiation dose reduction against surgical image quality requirements.
Integrated the intraoperative CBCT prototype with a surgical guidance system to assess real-time tracking and error detection.
Intraoperative CBCT demonstrated advances in spatial resolution and soft-tissue visualization while task-specific protocols minimized radiation exposure.
Guidance integration enabled precise tracking and visualization using up-to-date intraoperative scans, decreasing reliance on fluoroscopy and preoperative-only images.
The integrated imaging platform allowed intraoperative detection of surgical placement errors and suboptimal outcomes directly in the operating room.
