The uncles and aunts in the community came to the neighborhood Committee, expecting experts from Beijing Millennium Hospital to take them to the magical "ultrasonic world". Min Yang, director of Ultrasound Department of Beijing Millennium Monument Hospital, first introduced the function of ultrasound and its role in disease diagnosis in plain language, and then showed the mystery with vivid pictures and videos. "This film suggests coronary heart disease, this film suggests atrial septal defect, this is the ultrasound image of patients with aortic dissection, this is liver cancer ..." Director Yang's voice fell, and the atmosphere at the venue immediately became active. Director Min Yang gave a lecture on ultrasonic science "Hey! Very clear, just like watching a movie. " Old people share the changes of ultrasound images of various diseases with great interest, and think that "ultrasound" is really amazing-if there is anything wrong with the heart or liver, you can know it by taking a photo, and there is no harm. I admire our expert doctor. Such a complex image is dark and unpredictable, and doctors can always find the root of the problem. Finally, Director Yang designed an interactive session based on his speech. Everyone rushed to answer, complement each other, remind each other, and some even asked questions. Director Yang patiently analyzed and answered them one by one. After the vivid speech and humorous guidance of Director Min Yang, patients are no longer unfamiliar with ultrasound examination, and have a preliminary understanding of the function and role of ultrasound. It is important to increase patients' understanding and trust in our medical staff. At the same time, it also broadens the knowledge of our primary doctors, improves our diagnosis and treatment level, and benefits us and patients a lot. Next, we will join hands with the Department of Ultrasound, meet with experts from various professional groups, go into the community, be close to the grassroots, continue the popular science education, and do some work to improve the current tense doctor-patient relationship and improve the health level of the people.
