WebUS artifacts can be understood with a basic appreciation of the physical properties of the ultrasound beam, the propagation of sound in matter, and the assumptions of image processing. US artifacts arise secondary to errors inherent to the ultrasound beam characteristics, the presence of multiple echo paths, velocity errors, and attenuation errors. WebThe difference between the transmitted frequency and the received frequency is the Doppler frequency shift. The angle between the direction of blood flow and the direction of the …
WebJul 15, 2024 · Color Doppler system may use frame rates of 4 to 32 frames per second. The frame rate is operator-controlled. Increase for better resolution. 3. To better detect low-velocity flow, use a higher frequency transducer. 4. To decrease the effect of tissue or vessel wall vibrations, increase the color wall filter. WebGain is a uniform amplification of the ultrasonic signal that is returning to the transducer after it travels through the tissue. So rather than brightening the monitor, the image on the screen is whitened by a uniform margin, as …
