This study robotized fluoroscopic C-arms for surgical imaging, enabling precise positioning and advanced imaging capabilities. This innovation aims to reduce radiation exposure and improve surgical efficiency.

Area of Science:

  • Medical Imaging
  • Robotics in Surgery
  • Surgical Navigation

Background:

  • Fluoroscopic C-arms are essential surgical imaging tools.
  • Manual C-arm positioning is time-consuming, requires expertise, and can lead to inaccuracies.
  • Reproducing exact C-arm positions for follow-up imaging is challenging.

Purpose of the Study:

  • To develop a robotized C-arm system for enhanced surgical imaging.
  • To improve positioning accuracy and efficiency in surgical procedures.
  • To minimize radiation exposure for operating room staff.

Main Methods:

  • Equipped a standard C-arm with motors and encoders for full "robotization".
  • Developed intelligent software for C-arm control.
  • Performed a complete kinematic analysis of the fluoroscope.
