MRI-compatible step dynamometer

Design Award

  • Design Excellence Award Honorable Mention

Project Overview

In order to better understand the effect of exercise on patients with pulmonary hypertension, Professor Naomi Chesler would like to use magnetic resonance imaging (MRI) to accurately measure changes in blood pressure and flow of the pulmonary arteries during exercise. Our task is to develop an MRI-compatible exercise device for patients undergoing cardiac MRI scans. It should allow the patient to exercise while lying within the MRI bore and be adjustable so patients of varying fitness levels and sizes can generate a sufficient increase in cardiac output and heart rate.
