Knowledge point

Color-flow imaging

Color-flow imaging is an enhanced form of Doppler ultrasound technology. In a procedure similar to duplex ultrasound, it uses color to highlight the direction of blood flow. Vessels in which blood is flowing are colored red for flow in one direction and blue for flow in the other, with a color scale that reflects the speed of the flow.It can clearly understand the anatomical shape and activity of large blood vessels, and can visually display the direction, speed, range of blood flow, and whether there are blood flow disorders and abnormal pathways. The speed of blood flow determines the reflection frequency, which is represented by amplitude beam in spectral Doppler. The velocity of blood flow is fast, and the amplitude on the spectrum curve is high; the velocity of blood flow is slow, and the amplitude on the spectrum curve is low, so amplitude can accurately calculate the velocity of blood flow. Color Doppler images are displayed with different brilliance.

Color Doppler flow imaging

Color Doppler flow imaging system can simultaneously display B-type image and Doppler blood flow data (blood flow direction, flow velocity, flow dispersion) of dual ultrasound scanning system. Color power angio(CPA) detected the backscattered energy of blood cells in the blood flow, which did not distinguish the flow direction, and had nothing to do with the angle θ (the angle between the direction of sound wave and the direction of blood flow). CPA can improve the sensitivity of blood flow detection, especially suitable for displaying low-speed blood flow of small vessels, but can not show the direction of blood flow.
 

Annular probe

The principle of using the circular ring array dynamic segmented focusing method in mechanical sector-scan ultrasonic diagnostic equipment is the same as that of linear array dynamic focusing. Applying a proper delay to the electrical signal of each element can achieve focusing at any distance along the central axis, which is similar to the function of an acoustic lens, so it functions as an "electronic focusing lens".
