With the advancement and development of ultrasonic instrument technology, ultrasonic diagnosis has also made breakthroughs and expanded its clinical application range. Ultrasound diagnosis has become an important routine diagnostic method in modern clinical medicine, and has developed into an important monitoring method for a variety of interventions, operations, emergency care and monitoring. With the popularization of ultrasound instruments in urban and rural areas across the country, there have been problems of lack of ultrasound diagnostic professionals and different levels of medical diagnosis. Therefore, it is necessary to help ultrasound medical workers to master the basic theory of ultrasound medicine, learn advanced diagnosis and treatment methods, correctly and reasonably apply various ultrasound technologies to the clinic to maximize the potential of ultrasound diagnostic equipment.
General practice use (mainly divided into ultrasound diagnostic systems for cardiovascular, abdominal, superficial organs, fetus, abdominal large blood vessels and limb blood vessels. Superficial organs mainly include diseases of thyroid, breast, eye, testis, scrotum, etc. Generally, high-frequency probes are used. Abdominal organs are mainly divided into digestive system, urinary system, gynecology, including uterus, accessories and other diseases. Fetal diagnosis in normal fetuses in the early, middle and late stages, mainly observe fetal growth and development, examination of Amniotic fluid, umbilical cord, placenta. Vascular ultrasound diagnosis, including carotid artery, abdominal large blood vessels and blood vessels of limbs, to know whether there is plaque and stenosis in arteries, and whether there is thrombus in veins; for the heart, mainly detect whether there are abnormalities in intracardiac structure and hemodynamic changes.), remote diagnosis.
