High-frequency oscillatory ventilation (HFOV) is a ventilation technique used in patients with acute respiratory distress syndrome (ARDS). MRI can contribute to the understanding of the complex gas transport mechanisms in HFOV. One approach is the usage of phase contrast imaging. High flow speeds up to 40 m/sec and the small structures are a big challenge in this process. To achieve high spatial resolution on a trachea phantom a remote detection coil setup using an eight rung birdcage resonator for exciting the gas and two separate receive elements which can be placed on the tube was designed.
