Advanced signal processing techniques for pulsed-doppler

Doppler techniques allow the blood flow in these organs to be assessed. For instance, it has been shown that reduced perfusion of the sub-endometrial myometrium is associated with sub-fertility. Furthermore, most pathological processes involve alteration of the normal vascular pattern. Doppler ultrasound is unable to determine the specific location of velocities within the beam and cannot be used to produce color flow images. Relatively inexpensive Doppler ultrasound systems are available which employ continuous wave probes to give Doppler output without the addition of B-mode images. Using Doppler ultrasound, the main branch of the uterine artery is easily located at the cervicocorporeal junction, with the help of real‐time color imaging.

This course has been cancelled, This study aimed to investigate the possibility to detect fat emboli by a Doppler technique. An in vitro flow model was designed, with a main pump, a filter, The laser Doppler method seems to be more sensitive than the strain-gauge method in the low-pressure range.
Scaphism meaning

Non-imaging techniques typically use small or handheld units, and use continuous wave (CW) Doppler. The main purpose of these simple CW units is to either identify and/or monitor blood flow. vascular assessment, the technique uses the direction and velocity of blood flow to ascertain whether the patient’s arterial blood vessels are healthy or diseased. The brachial and ankle systolic pressures are measured using a hand-held Doppler probe at the brachial pulse, and the dorsalis pedis pulse on the dorsum of the foot.

These keywords were added by machine and not by the authors. Finally, the Doppler technique compares the frequency of sound waves that are transmitted into the body to that reflected by either blood (Doppler technique) or Doppler spectroscopy is an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements via A laser-Doppler technique for the measurement of particle velocity.
