An open-source platform for simulating internal organ motion: Preliminary results

Motion-correction techniques require an objective quantitative assessment under controlled conditions. In this work, we present an open-source platform for simulating internal ‘organ’ motion under realistic scan conditions. The phantom was composed of two partitions which include a high-resolution inner compartment translated in space using a Lorentz force, within a larger body-like second compartment. The motion phantom was controlled using custom-made software and was tested with a radial MR sequence, demonstrating motion-resolved capabilities.
