MR Compatible Haptic Device for Monitoring Neuro Circuits under fMRI Environment

  • Functional magnetic resonance imaging (fMRI) is often used to explore the activity of widely distributed neural circuits related to sensorimotor and cognitive functions. However, there is currently no device that satisfies the experimental and environmental needs of fMRI studies exploring the neural control of movement in the non-human primate (NHP) model. Here, we are developing devices capable of both monitoring and perturbing the movements of NHPs during fMRI. The combination of MR compatible devices and fMRI promises to aid in translating novel therapies developed in the NHP model into effective treatments for human disease

  • IEEE/ASME Transacations on Mechatronics 2013 – Development of a Parallel Actuation Approach for MR-Compatible Robotics Abstract — In recent years, the use of robotics to augment MRI diagnostic and interventional procedures has increased significantly. However, the demanding MRI environment precludes the use of most common actuation approaches. Alternative actuation concepts have been proposed but these solutions do not lend themselves to linear control structures. We present a new actuation method, using the motion of parallel ultrasonic motors ...
