80029-2	Left ventricular outflow tract Maximum blood flow velocity during systole by US.doppler

Part Description

LP6617-7 US.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.
