Plantarflexion Ergometry (PE), in conjunction with Magnetic Resonance Imaging (MRI), has shown to be a useful technique in the research and study of Peripheral Artery Disease (PAD) in patients' extremities. A number of studies have conducted PE experiments with favorable results. However, the devices reviewed lack the MRI compatibility option. They are often not designed to measure angular displacement, which accounts as the displacement variable within the calculated torque and work function. In this research, a fully MRI compatible PE was constructed using commercially available parts. To reduce interference and imaging noise during MRI PE, RF (Radio Frequency), magnetic shielding was designed, constructed, and implemented. Mathematical models that quantify the effectiveness of magnetic shielding and interference were derived and analyzed. The combination of the constructed MRI shielding materials and mathematical modeling may enable researchers to perform more complex and precise measurements in the hopes of expediting diagnostics and treatment for PAD.
