1.Development of domestic ultrasound in China In December 1958, Professor Zhou Yongchang of the Sixth People’s Hospital of Shanghai (Sixth People’s Hospital of Shanghai Jiaotong University) first reported the use of pulsed A-type ultrasound detector to detect liver, stomach, gravida, cervical cancer and breast, and to analyze and interpret their echo images. Since then, Shanghai Sixth People’s Hospital has been known as “the birthplace of ultrasound diagnosis in China”. In 1960, Shanghai First Medical College first developed A and BP type ultrasonic diagnostic instruments, which were used by Shanghai Zhongshan Hospital to detect occupying liver lesions, ovarian cysts, uterine fibroids, staphyloma, teratoma and other diseases. In 1961 and 1962, Beijing and Wuhan successively used B-type ultrasound imaging diagnostic method for clinical use and reported in national academic conferences. In 1961, M-type ultrasonic diagnostic instrument was made in Shanghai Zhongshan Hospital, and Zhou Yongchang and Wang Xinfang used it to detect fetal heart and diagnose early pregnancy, and Zhou Yongchang used M-type ultrasonic to trace the fetal heart of early pregnancy, which was 3 years earlier than foreign countries. In 1965, Beijing Military General Hospital used Doppler to detect fetal heart, and later used to monitor placenta, umbilical cord, arteries and veins to determine certain diseases. In 1982, pulsed Doppler ultrasound diagnosis was applied to diagnose congenital heart disease. Subsequently, with the continuous development of ultrasound diagnosis and the increasing number of ultrasound diagnostic techniques, ultrasound has continued to develop in the field of medical diagnosis and treatment. Currently. Three-dimensional ultrasound, color ultrasound, intracavitary ultrasound, intravascular ultrasound, high-focus ultrasound (HIFU), ultrasonography, etc. are widely used in clinical practice. The current ultrasound profession has not only been limited to the diagnosis of clinical diseases, but also applied to the treatment of diseases, to relieve patients’ pain and reduce the trauma of treating diseases. With the continuous development of ultrasound medicine and the continuous improvement of practitioners’ level, interventional ultrasound has been developing. At present, hospitals in Beijing, Shanghai and Guangzhou, such as Union Hospital, General Hospital of the Chinese People’s Liberation Army, Peking University Cancer Hospital, Shanghai Sixth People’s Hospital, Shanghai Zhongshan Hospital and Guangzhou Affiliated Hospital of Sun Yat-sen University have carried out ultrasound interventional business earlier, and the technology has continued to mature, forming nationally renowned experts such as Dong Baowei, Chen Minhua, Hu Bing, Wang Wenping and Lu Mingde. In the past, people often called the Department of Diagnostic Ultrasound as “Ultrasound Room”, but the times are developing and people’s concept should be updated. The current ultrasonic diagnostic department can no longer be compared with the previous “B ultrasound room”, B-type ultrasound is only one of the current ultrasonic diagnostic techniques, the current ultrasonic diagnosis is a combination of B-type ultrasound, color ultrasound, Doppler ultrasound, three-dimensional ultrasound, interventional ultrasound and other ultrasonic diagnostic techniques. At this time, ultrasound diagnosis is not the “B ultrasound”, we should abandon the old thinking, constantly update the concept, and keep pace with the times. 2, the development of ultrasound practitioners Overview of China’s ultrasound diagnosis began in the 1950s, the beginning of the profession, there is no ultrasound professionals, ultrasound practitioners are mostly other professional “transferred” to come, which has both clinical doctors and nurses, practitioners vary, which has caused the uneven level of ultrasound diagnosis, and This has left an impression that ultrasound practitioners are not doctors. Later, medical schools opened ultrasound medicine, and formed a master’s and doctoral training system for ultrasound medicine, from then on ultrasound medicine continued to become more professional and standardized. Most of the current ultrasound practitioners are medical talents from formal medical schools, who have received formal medical training and systematic training of medical theory system, with clear diagnostic ideas and advanced technology, who know both clinical and ultrasound, laying a solid foundation for ultrasound professional diagnosis and interventional treatment and clinical application of new technologies. 3.Sub-discipline of ultrasound With the continuous development of ultrasound diagnosis and interventional therapy, the sub-discipline of ultrasound is becoming more and more detailed, and the division of labor is more clear, which facilitates the standardization and development of different disciplines. At present, ultrasound is divided into the following sub-disciplines: 1) abdominal ultrasound discipline. This includes ultrasound diagnosis of abdominal organs such as digestive system, urinary system and retroperitoneal diseases; 2) small organs and superficial ultrasound. This includes ultrasound diagnosis of thyroid, breast, testis, epididymis, spermatic cord and superficial masses; 3) Peripheral and abdominal vascular. It includes ultrasound diagnosis of abdominal vessels, extremities and neck vascular diseases; 4) Ultrasound of motor system, extremity joints and muscles; 5) Cranial ultrasound; 6) Ultrasound of gynecology and obstetrics; 7) Ultrasound of heart diseases; 8) Ultrasound of interventional medicine. Ultrasound intervention belongs to the discipline of ultrasound medicine, in the development of their own theoretical system and technical specifications, ultrasound intervention is currently a more important development direction of ultrasound, there have been significant results, the future will be more promising, the sky is wide.
