MRI-Compatible Surgical Robotics and "Closed-Loop" Imaging
Until recently, the high magnetic field of an MRI made it impossible to use traditional robotics. By early 2026, the use of non-ferromagnetic
piezoelectric and pneumatic actuators has allowed for robotic interventions inside the MRI borehole.
Real-Time Neurovascular Navigation: Surgeons now use MRI-compatible robotic arms to guide needles into brain tissue while the patient is being scanned. This provides a live, high-contrast map that accounts for "brain shift"—the slight movement of brain tissue that occurs once the skull is opened.
Automated Motion Compensation: For cardiac and spinal interventions, the robot utilizes a feedback loop from the MRI data to "predict" the patient's breathing or heartbeat, micro-adjusting the instrument's position to maintain sub-millimeter accuracy.
