Abstract

A method is described for obtaining the three-dimensional spatial distribution of roentgen opacity within the intact canine thorax. Video recordings of multiple roentgenographic projections are digitized during rotation of the dog in the X-ray field to provide the data required for the reconstruction of a sequence of parallel spatially adjacent cross-sectional images of the thorax or heart over their entire anatomic extent at 1 60second intervals in time. The accuracy of the technique is demonstrated with test objects and excised canine hearts, and the capability for high temporal resolution is illustrated by the cross-sectional reconstruction of a metabolically supported, isolated working canine left ventricle at different phases of the cardiac cycle. These data, along with simultaneous measurement of intracardiac and transmural pressures, provide the determinants required for estimations of dynamic myocardial length/tension relationships that are necessary for the quantitative assessment of cardiac contractility and reserve.
