          The diagnosis of many cardiovascular diseases can 
						benefit from imaging during a cardiac stress test. The 
						purpose of this study was to develop a low-cost exercise 
						device that could be used within the confines of an MRI 
						bore during a cardiac MR scan and also provides measures 
						of work. The device was designed to create exercise 
						stress via a stepping motion by the subject in a supine 
						position while minimizing unwanted chest movement and 
						upper body translation. Our pilot testing results 
						confirmed substantial increase in heart rate (+85%), 
						cardiac output (+100%), mean aortic flow (+65%) and mean 
						pulmonary artery flow (+%101) post-exercise.
