“…The gamma ray densitometer described in this paper differs from previously reported systems (Small, Miller, Leiner, Strauss and Abramowitz 1963, Zelefsky and Schultz 1968, Cattrell, Franklin and Kirkpatrick 1970 in two important respects; it is designed to measure regional ventilation and perfusion and the system has a digital output to facilitate data processing.…”

AN ECG-triggered multisweep method for the collection of low-energy gamma ray absorption data in normal and cancerous tissue has been developed, resulting in digital perfusion curves with reliable statistics. The small intensity modulation ( approximately equal to 1.2%) due to lung perfusion is detected and separated from the much stronger intensity variations caused by ventilation in a satisfactory way. During this non-invasive test the patient is supine and breathes smoothly.
