Part Description

LP189366-0   US.tissue doppler
Doppler ultrasound detects the shift in frequency of ultrasound signals reflected from moving objects. Conventional Doppler techniques assess the velocity of blood flow by measuring high-frequency, low-amplitude signals from small, fast-moving blood cells. In tissue doppler ultrasound, the same Doppler principles are used to quantify the higher-amplitude, lower-velocity signals of myocardial tissue motion.
