A new quantitative imaging device, the Dynamic Spatial Reconstructor (DSR), is described. Because, unlike commercially available computed tomography scanners, it obtains stop-action (0.01 second) images of a volume rather than a slice at a repetition rate of 60 volumetric scans per second, the DSR is particularly well suited for the study of ischemic heart disease. Its capabilities for recording the transit and dilution of contrast media within the coronary vasculature and all regions of the myocardium simultaneously with regional and global myocardial mechanics are being evaluated as a research tool for physiologic and ultimately clinical investigations.
