Term Description

Pressure gradient measure proximal to the aortic valve. Mean velocity measured proximal to the aortic valve.

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.
