Synopsis

Keywords: RF Arrays & Systems, RF Arrays & Systems, MSK

Motivation: Many musculoskeletal disorders cannot be detected in static MRI, making surgical intervention necessary.

Goal(s): Our Goal was to enable motion controlled dynamic MRI to potentially add diagnostic findings and reduce surgical interventions.

Approach: We advanced our apparatus for controlled passive movement of the foot (Robotic Motion Device) and implemented an adapted 16-channel Ankle Coil for accelerated imaging.

Results: Combining the Robotic Motion Device and the 16-channel Ankle Coil allowed us to perform controlled passive foot movement and acquire high SNR images.

Impact: The combination of a Robotic Motion Device and an adapted 16-channel Ankle Coil enables dynamic image acquisition with controlled passive movement of the ankle joint, potentially adding and improving diagnostic findings and reducing surgical interventions.
