A novel metal-free motion phantom based on a simple pneumatic rotary motor with optical rotational speed measurement is presented. The phantom facilitates the simulation of various motion speeds from 0.05 to 0.5m/s by air-pressure adjustment. It is a suitable tool for for both qualitative and quantitative evaluation of real-time MRI methods.
