Three and Four Dimensional Characteristics of Color Doppler M-Mode Echocardiography

This article introduces a novel approach to displaying three and four-dimensional color M-mode echocardiography, focusing on the descending aorta. Traditionally, echocardiography primarily utilizes B-mode and M-mode imaging, but this study innovatively explores the visualization of color Doppler M-mode echocardiography. By analyzing Doppler data extracted from the descending aorta using a vivid-6 echocardiography device, the authors developed a Windows-based software for comprehensive analysis. The method involves extracting data from one complete heart cycle, analyzing color-coded data of systole and diastole, and representing each pixel's Doppler data on a three-dimensional chart. Additionally, the authors propose a method to spread a heart cycle in 360 degrees around the Y-axis, resulting in a four-dimensional visualization. The results demonstrate the visualization of major and minor flows in the descending aorta, with potential applications in assessing conditions such as aortic valve insufficiency.
