title: A retractable, multi-view gas delivery apparatus.
abstract: The author described a radioxenon gas delivery apparatus which permits ventilation imaging of the lung in multiple positions during the rebreathing (equilbrium) phase following the administration of a single dose of tracer. A single, rapid check for gas leakage is outlined. This can be done before xenon is introduced into the system thus minimizing the chance of xenon escaping. The unit is suspended from the ceiling and retracts out of the way when not in use. A parts list is included.
