ABSTRACT
Based on the analyses of coronary physiology and the principle of fluid mechanics, a Computer Assistant Analysis (CAA) system was built with coronary angiography hardware as well as development of software. With the CAA system,the coronary blood velocity was measured by "Digital Tracing Technique (DTT)" method, and related analysis was performed with Doppler blood the silk (the standard of gold) or TIMI surname blood in 80 cases clinical cases. The results showed a positive correlation (r1 = 0.79, p1 < 0.001) between Vmean (The average blood velocity of LAD, 17.98 +/- 5.66 cm/s) by measurement using digital tracking technique and Average peak velocity (APV17.70+/-5.77 cm/s) at approximate and distal of LAD by measurement using Doppler wire; and a negative correlation (r=-0.51, P<0.05) with TIMI surname blood (18.58 +/- 6.46 cms/ s vs 28 +/-7.5 frames). The research and clinical application result enunciates The coronary blood velocity dynamics measured by DTT method is a scientific index applicable to clinical examination for coronary diseases, which would be useful in enhancing the diagnostic ability integrated in anatomy and physiology during conventional angiography.
