Encoder Designed for Extreme Electromagnetic Fields
Prior to the MR318, engineers had no commercial solution for measuring continuous position within an MRI chamber. Motors or actuators could be hydraulic or pneumatic but no commercial, non-metallic position sensor existed. A homemade fiber optic proximity/limit switch was the best solution, but this was awkward to design, package, and could only provide position information at discrete points. The advent of the MR318 enabled fully-functional motion control apparatus with closed-loop feedback.
