The purpose of this study was to design and build a low-cost, non-ferromagnetic LV motion phantom for use with cardiac MRI that is able to produce physiologically realistic LV wall thickening and rotation. Wall motion and rotation are modeled using separate phantoms housed within a common enclosure. The phantoms are easy to assemble and are constructed entirely of non-ferromagnetic materials, Results were physiologically realistic and reproducible, with standard deviations below 1.7% for strain and 1.1 for rotation. These phantoms could be of benefit when developing new cardiac MRI techniques and could potentially reduce development costs.
