N2 - A method is described for obtaining the dynamic spatial distribution of x-ray densities throughout parallel cross-sectional planes bisecting the thorax of living, anesthetized dogs. Cross-sectional images of the thorax, lungs and/or heart covering their entire anatomic extent at 1/60 second intervals in time are determined from video recordings of multiple x-ray projections obtained by rotating the dog through 180 degree in successive angular increments. These data, along with simultaneous recordings of transmural pressures, provide the basic determinants required for detailed analysis of cardiac and pulmonary function, including accurate measurements of the dynamic regional changes in shape, dimensions and perfusion of the heart and lungs and the length/tension relationships within the myocardium and pulmonary parenchyma. The development of equipment and techniques to provide these measurements, which cannot be obtained by conventional biplane angiographic methods, in a clinical diagnostic setting is technologically feasible.
