Abstract
Distribution evaluation of regional lung ventilation is obtained by placing a radionuclide and an array of scintillation detectors on opposite sides of a subject from evaluation units. Each of the signals from evaluation units of the detectors is stored in a memory. The signals are compared in a comparison block, and the comparison is recorded by a recorder.
