Project Overview

The goal of the project is to design and build a lower leg exerciser that is compatible with MR imaging, ultrasound, and echocardiography so that can conduct cardiopulmonary exercise testing on patients and healthy volunteers during imaging studies. The device must have repeatable loads that can be measured and displayed to the patient for biofeedback.

Project Status

We have decided to continue on with this project despite the existence of other similar devices. We believe that our device will be differentiated enough to warrant merit.
