This study introduces a novel telerobotic device for MRI-guided interventions. The nonmagnetic robot achieves high precision for minimally invasive therapies, demonstrating its potential in advanced medical procedures.

Area of Science:

  • Medical Robotics
  • Interventional Radiology
  • Magnetic Resonance Imaging (MRI)

Background:

  • Medical robots are increasingly developed for various applications.
  • Magnetic Resonance Imaging (MRI) offers excellent soft-tissue contrast, making it attractive for image-guided therapies.
  • Interventional procedures require precise instrument control within the MRI environment.

Purpose of the Study:

  • To present a telerobotic device designed for CT- and/or MR-guided radiological interventions.
  • To describe a robotic system for accurate needle insertion during MR-guided spinal disease therapy.

Main Methods:

  • The robot was constructed using nonmagnetic materials, including polyether ether ketone (PEEK) and fiber-reinforced epoxy, to ensure MRI compatibility.
  • Actuation was achieved using ultrasonic and pneumatic motors, avoiding electromagnetic interference.
