Fig. 4From: Exercise cardiovascular magnetic resonance: development, current utility and future applicationsCustom supine stepper ergometer. An example of a supine stepper ergometer utilised in research at the University of Wisconsin [87]. a. The ergometer outside the CMR-scanner. b- The ergometer in use. The ergometer allows for exercise via an up/down motion, a technique which is reported to cause less movement artefact than the cycle ergometer at the cost of less muscle mass recruitment and thus lower achievable maximal heart ratesBack to article page
