At the same time, Doppler ultrasound technology began to be widely used in other fields, such as obstetrics and neurology.
Early 21st century: With the continuous development of computer technology, the functions of Doppler ultrasound machines have been continuously improved, and the imaging quality and speed have been further improved. At the same time, the size and price of equipment are gradually becoming more rational, making its popularity in medical institutions increasingly deepened.
Development in recent years: The development of Doppler ultrasound technology is still in progress. New probe design, the application of intelligent technology and the addition of artificial intelligence have enabled Doppler ultrasound machines to continue to improve in terms of imaging quality, ease of operation, etc., providing Medical diagnosis provides more reliable and accurate means.
Advantage:
Rich blood flow information: Doppler ultrasound machines can provide blood flow information such as blood flow speed and direction, which is beneficial to the diagnosis and treatment of cardiovascular diseases.
High accuracy: The Doppler ultrasound machine has high accuracy in measuring blood flow velocity and can provide reliable diagnostic basis.
Disadvantages:
Average imaging quality: Compared with black and white ultrasound machines, Doppler ultrasound machines are slightly inferior in imaging quality and cannot clearly display tissue structures.
3. Color ultrasound machine
Development history: Color ultrasound technology is developed based on black-and-white ultrasound technology and Doppler ultrasound technology, and can display tissue structure and blood flow information at the same time.
1970s: Ultrasound technology began to be widely used in the field of medical imaging. Researchers tried to introduce color technology into ultrasound imaging to improve the information content and quality of the image.
1980s: With the development of computer technology, color ultrasound technology gradually matures. The advent of the first color ultrasound imaging system, which can simultaneously display tissue structure and blood flow information, greatly improves the accuracy and reliability of medical diagnosis.
