Quantitative analysis of three-dimensional images of the left ventricle generated with the dsr

Accurate description of anatomy and function of the heart requires the ability to measure a three-dimensional object changing shape in time. The Dynamic Spatial Reconstructor (DSR) is an imaging system capable of making these measurements. DSR data are immense in quantity, and require powerful digital computing systems for generating and manipulating images. AD example is presented where the DSR system is used to quantitate local canine myocardial function in vivo. Application of this method could result in a more comprehensive and more accurate understanding of function in the healthy and pathologic heart.
