pulsed Doppler

pulsed Doppler

a type of Doppler device that transmits a short-duration burst of sound into the region to be examined. The Doppler-shifted signals are processed from a limited depth range. The depth range is determined by a sample gate whose position and size usually can be selected by the instrument operator.

Mitral E velocity (ME), mitral A velocity (MA), mitral E wave deceleration time (MEDT), and LV isovolumic relaxation time (IVRT), defined as time period between the termination of aortic systolic wave and beginning of ME, were measured by locating the sampling volume cursor of pulsed Doppler in the apical four chamber position at 5 mm above the mitral leaflets tips.

Moving target indication (MTI) is a technique that enhances the detection and display of moving radar targets that can be implemented with pulsed Doppler radar in order to exploit the differential Doppler shifts between real targets and clutter.
In 1982, Rune Aaslid used a pulsed Doppler transducer to propagate 1 to 2 MHz waves through the adult human skull and for the first time was able to accurately determine the velocity of blood flow through specific cerebral arteries encircling the base of the brain.
