This study introduces a 3D reconstruction tool for virtual fluoroscopy, enhancing surgical planning and assessment by adding depth information to 2D X-ray images without additional radiation exposure.

Area of Science:

  • Medical Imaging
  • Surgical Technology
  • Orthopedics

Background:

  • Virtual fluoroscopy systems typically display tracked instruments as 2D shadows, lacking crucial depth information.
  • This limitation hinders precise surgical planning and assessment of instrument or anatomy positioning.

Purpose of the Study:

  • To present an innovative tool for 3D reconstruction in virtual fluoroscopy.
  • To improve the visualization of instrument and anatomy positioning during surgical procedures.
  • To aid in the planning and assessment of surgical interventions without requiring additional X-ray imaging.

Main Methods:

  • Development of an extra tool for 3D reconstruction integrated into virtual fluoroscopy.
  • Application of the tool to visualize complex orthopedic cases.

Main Results:

  • The tool successfully provides depth information, clarifying the spatial relationship of instruments and anatomy.
  • Demonstrated utility in two distinct orthopedic cases: displaced subtrochanteric fracture and slipped upper femoral epiphysis.

Conclusions:

  • The developed 3D reconstruction tool significantly enhances virtual fluoroscopy by incorporating depth perception.
  • This advancement offers a valuable, radiation-free method for surgical planning and intraoperative guidance in orthopedic procedures.
