Transcutaneous measurement of blood velocity profiles and flow [PDF]
Cardiovascular Research, 1973 A comprehensive report is presented of the application of a pulsed ultrasound Doppler velocity meter for transcutaneous measurement of time varying velocity, velocity profiles, and instantaneous flow in arteries of anaesthetized dogs. The procedure used to provide direct velocity and flow calibration using the Doppler equation is outlined.

Revealing Intraosseous Blood Flow in the Human Tibia With Ultrasound
JBMR Plus, 2021 Intraosseous blood circulation is thought to have a critical role in bone growth and remodeling, fracture healing, and bone disorders. However, it is rarely considered in clinical practice because of the absence of a suitable noninvasive in vivo ...
