Physicians face high radiation exposure during CT-guided procedures. A novel robot for needle manipulation significantly reduced physician radiation exposure during computed tomography (CT) fluoroscopic-guided interventions.

Area of Science:

  • Medical imaging and interventional radiology.
  • Robotics in medicine.
  • Radiation safety in healthcare.

Background:

  • Physicians performing interventional procedures using computed tomography (CT) fluoroscopic guidance risk significant radiation exposure to their hands.
  • Minimizing occupational radiation dose is crucial for healthcare professionals in interventional radiology.

Purpose of the Study:

  • To evaluate the efficacy of a novel robotic system in reducing physician radiation exposure during CT fluoroscopic-guided percutaneous interventions.
  • To assess the safety and feasibility of robotically guided needle manipulation in clinical settings.

Main Methods:

  • Development of a robotic system capable of holding, orienting, and advancing needles under CT fluoroscopic guidance.
  • Performance of 23 percutaneous interventions using the robotically guided system, controlled via computer or joystick.

  • Measurement of physician radiation exposure during the procedures.

    • Main Results:

    • Twenty-three robotically guided percutaneous interventions were successfully completed without any complications.
    • Physician radiation exposure during the CT fluoroscopy-guided procedures was found to be negligible.
    • The robotic system demonstrated effective control over needle manipulation.

    Conclusions:

    • A robotic system can be safely and effectively used for needle guidance in CT fluoroscopic procedures.
    • The implementation of this robotic technology significantly minimizes radiation exposure to physicians' hands.
    • Robotic assistance holds promise for enhancing safety in interventional radiology practices.
