Popis: | A lung model taking into account essentially the same assumptions as Winlove et al. (1975) and introducing the reduction of the concentration of tracer in the lung due to radioactive decay is derived. Using a computerized gamma camera and the model it is possible to determine the regional specific lung ventilation using the relatively short-lived 81Krm as radioactive tracer. |
