This study integrated a robotic system with CT scanning for minimally invasive procedures. The robotic system accurately guided a virtual needle during a pig biopsy, demonstrating its potential for precise interventions.

Area of Science:

  • Medical robotics
  • Minimally invasive surgery
  • Medical imaging

Background:

  • Pre-operative planning and intra-operative computer interfaces are crucial for minimally invasive interventions.
  • Integrating robotic systems with imaging modalities like CT scanners enhances procedural accuracy and safety.

Purpose of the Study:

  • To investigate the efficacy of an active robot integrated with a CT scanner for pre-operative planning and intra-operative control in minimally invasive interventions.
  • To evaluate the accuracy of a robotic system in guiding a virtual needle during a CT-guided biopsy procedure.

Main Methods:

  • An active robot integrated with a CT scanner was utilized.
  • Pre-operative planning involved superimposing a virtual needle on CT slices.
  • A pig biopsy study was conducted to test the robotic system's accuracy and intra-operative control capabilities.

Main Results:

  • The robotic system successfully guided a virtual needle congruent with the planned path.
  • Intra-operative controls allowed needle insertion while minimizing the interventionalist's exposure to X-ray radiation during CT fluoroscopy.
  • Post-insertion comparison showed sufficient congruence between the imaged and virtual needles.

Conclusions:

  • The integrated robotic system provides accurate pre-operative planning and precise intra-operative guidance for minimally invasive interventions.
  • This technology has the potential to improve safety and accuracy in CT-guided procedures by keeping operators out of the direct X-ray beam.
