the presentation of 2D, real time Doppler- shift information in color superimposed on a real-time, gray-scale, anatomic, cross-sectional image. Flow directions toward and away from the transducer.
a change in frequency caused by reflector motion
range of brightnesses between white and black
a reproduction, representation, or imitaiton of the physical form of a person or thing
an anatomic image presented in a rectangular format
ultrasound imaging in which pulses are reflected and used to produce a display
a line produced on a display that represents ultrasonic echoes returning from the body. A sonographic image is composed of many such lines.
an anatomic image presented in a pie-slice shaped format
medical 2D, cross-sectional, and 3D anatomic flow imaging using ultrasound
the presentation of Doppler information in a quantitative form of Doppler shift versus time. Visual display of a Doppler spectrum.
a device that converts energy from one form to another
sound having frequency greater than what humans can hear, that is, greater than 20 kHz.
