Color ultrasound generally 3 probes, for lesions can use different frequencies of the probe to explore, a more comprehensive understanding of the size of the lesion, the contours and nature of the lesion, and a color ultrasound machine requires hundreds of thousands or even millions of dollars. It usually has B ultrasound, black and white B ultrasound only a probe, usually only check the abdominal cavity, its image resolution is also better than ordinary black and white ultrasound. The price of a color ultrasound is at least several times that of a black-and-white ultrasound. A black-and-white ultrasound machine costs tens of thousands of dollars. Color ultrasound is short for color Doppler ultrasound. Color ultrasound can produce color Doppler ultrasound blood flow images, which can significantly improve the diagnosis of lesions.
The color Doppler ultrasound has a high diagnostic value for the benign and malignant lesions of the liver, gallbladder, spleen, kidneys and other intra-abdominal organs which are difficult to be identified by ordinary ultrasound. It consists of five diagnostic ultrasound methods: M-mode, pulsed Doppler, continuous Doppler, and color Doppler flow imaging. Therefore
