What Is Color Doppler Ultrasound, What Are the Clinical Applications?

  Author:MeCan Medical–ultrasound machine manufacturers

Color Doppler ultrasound is to increase the Doppler blood flow imaging and spectrum Doppler on the basis of B -ultrasound. It can dynamically and quantitatively quantitatively quantitatively observe the direction, speed and the motion status of specified regional tissues. It has nothing to do with color, which contains a series of data required by clinicians such as speed, frequency and amplitude.

The principle of color Doppler ultrasound is the "Doppler effect". The Doppler effect is used to detect the movement of red blood cells, and the direction of these movements is expressed in color, and a color blood flow map is formed. At the same time, parameters such as bleeding flow speed and resistance index can be calculated. In order to be unified, we generally marked the blood flow towards the probe to the red, and the blood flow of the probe marked the blue. This is not the constant that can be adjusted by the habit of the inspector. The principle of color Doppler ultrasonic is ultrasonic, which is a mechanical vibration wave. It has the characteristics of non -invasiveness, convenience and efficiency. It has no radiation. Therefore, it is widely used in clinical diagnosis and treatment.

The Doppler ultrasound machine is mainly composed of the following parts. The probe is equivalent to our X -ray tube. The echo received by the ultrasonic wave after passing through the tissue organs is processed to form an image on the display. By controlling panels and touch screens, we can adjust the check parameters in real time to obtain more perfect images. There is a probe socket on the host, which connects different probes through it to meet different inspection needs.

Color Doppler ultrasound can judge the direction of blood flow, fast and slow, blood flow, etc., mainly for sports tissue organs, such as blood flow, heart, etc., compared to a single B -ultrasound, more color ultrasound functions, and their image resolution is also excellent. For ordinary black and white B -ultrasound.

Through Doppler observation, the blood flow speed changes, blood flow status, and tissue echo -cutting image of the tissue -echoed surface images at different cycles are observed. After combining it, to determine whether the tissue organs have lesions, the degree of lesions, and the nature of the lesion. Early discoveries can be discovered more small lesions, an early diagnosis rate of the disease can be improved, and the details of the surrounding and internal changes can be displayed more clearly, and the accuracy of the diagnosis can be improved, especially the diagnosis of some masses is also valuable.
