A portable, low field, MR Device is being designed for use in the ICU. It was tested on healthy subjects and used to measure lung density changes during a 3.5 minute breathing protocol. A regional stress index, i.e. regional lung density vs. lung volume was measured. Gravitational differences were also observed.
