Motion is one of the main challenges in MRI, including interventional MRI. While many dynamic imaging and motion compensation techniques have been created, comparisons and validation are difficult, since it is difficult to reproduce in vivo motion for multiple experiments. This work proposes the design and development of a 1 Degree-of-Freedom hydrostatically actuated MRI-compatible motion platform, which can reliably reproduce programmed motion for dynamic MRI experiments.
