  • Integration of custom-designed MR imaging coils for enhanced anatomical visualization.
  • Validation of targeting accuracy using optical tracking, MRI-guided phantom studies, and a cadaveric evaluation.

    • Main Results:

    • Mean absolute errors of 0.97 mm (position) and 0.46° (angle) in free space.
    • System-level accuracy of 1.38 mm (position) and 1.08° (angle) in MRI-guided phantom studies.
    • Cadaveric validation demonstrated clinical workflow accuracy with errors of 2.11 mm (position) and 3.32° (angle), alongside minimal image degradation (<12.26% SNR variation).

    Conclusions:

    • The developed pneumatically actuated robotic assistant is suitable for MRI-guided stereotactic neurosurgery.
    • The system achieves high targeting accuracy and is compatible with intraoperative MRI guidance.
    • The proposed clinical workflow and integrated imaging coils facilitate precise and safe neurosurgical interventions.
