What Is Tissue Doppler Echocardiography?

Tissue Doppler echocardiography, also known as Doppler tissue imaging, is a new technique for detecting and evaluating myocardial motion. It is based on the traditional color Doppler instrument for detecting the blood flow in the heart cavity. By changing the Doppler filtering system, the high-speed, low-amplitude frequency shift signal generated by the blood flow in the heart cavity is removed, and myocardial motion is generated The low-speed, high-amplitude frequency-shifted signals are processed by related systems and displayed in color coding, which can quantitatively measure the wall motion.
