Dynamic Display of Heart Potential Images with Parallel Processing
Body surface potential mapping has been shown to improve the diagnostic accuracy of certain cardiac electrophysiological disorders. In order to display heart potential distribution maps dynamically in color graphic, we have developed a high-speed data acquisition and presentation system based on double parallel processing technique. The data presentation system consists of 16 parallel processing elements. Each processing element includes a local CPU and arithmetic processing unit (APU). Double parallel processing can be accomplished between the local CPU and APU in each processing element. By applying this double parallel processing technique we can achieve the dynamical display of heart potential distribution with good precision. Clinical application of this electrocardiographic mapping system should significantly increase the understanding of certain heart diseases. These double parallel computations may be adapted for use in other fields of computer graphics.
