Abstract
To obtain gated respiratory cycle imaging, we made an experimental device in which siglals of the respiratory cycle are monitored with a thermistor. The signals of the respiratory cycle are utilized to reconstruct pulmonary dynamic images in multiple sequential frames. Application of this device adds the dimension of time to the resolution of regional ventilation. The device has the potential for separating tidal and residual components, and way be useful for studying the pathophysiologic aspects of regional ventilation.
