This technique is a form of Doppler measurement referred to as Blood Flow Imaging (BFI). It can indicate blood flow directionally in addition to measuring velocity.
A Transcranial Doppler is a test used to test blood flow velocity as is flows through the brains blood vessels. Through emitting a high pitched sound, an ultrasound probe is able to measure the velocity of the blood flow.
The sounds they measure and listen to when doing a transvaginal ultrasound and tell you you are not pregnant are ultrasounds.
Ultrasound is used to measure and record living cells in the body, i.e when a woman is pregnent they scan the womb and measure the baby's heartrate.
It is a measure of speed in a specific direction
velocity
Air velocity in ventilation systems
A Doppler ultrasound is used to measure the speed of blood flow in the body. This non-invasive imaging technique uses sound waves to detect movement and produce pictures of blood vessels and the flow of blood within them.
In order to measure velocity you need displacement (a start location and an end location) and time.
are a measure of angular velocity whereas metres per minute are a measure of linear velocity.
Because acceleration is the rate of change of velocity: it is a measure of how quickly velocity is changing.
velocity = distance travelled/time taken to travel that distance
Speed and Velocity are the same thing, it is a measure of rate of change of position of an object.
