In order to image function in the free breathing lung with high temporal and special resolution, we have developed a passive, mechanically controlled MR-friendly gas delivery device capable of real time dosimetry and end-tidal gas measurements that can be used in combination with a non-rigid image registration technique. These dynamic images can thus be translated into comprehensible quantitative maps of lung ventilation and gas exchange. In order to image the lung continuously during normal breathing, we have also developed a fast-acquisition pulse sequence that uses diaphragm position to facilitate image reconstruction.
