<p> ' 超声医学作为现代医学影像学中发展最快、渗透性最强、实用性最强的新兴学科，自20世纪80年代以来，以其方便、准确、无创等优点在临床上得到了广泛应用。随着声学物理技术的深入研发和现代计算机技术的快速发展，超声医学已经从早期的一维超声发展到实时二维超声、三维超声、彩色多普勒超声，甚至出现了实时动态超声造影、超声图像融合导航、介入超声等最新智能技术。它已成为一种集临床诊断和治疗功能于一体的新型医学影像系统。本书的创作旨在帮助更多人了解超声医学及其新技术在临床实践中的发展和应用。本书由超声医学专家用通俗易懂的语言向公众介绍超声医学的起源、发展、现状和前景。同时，从超声医务工作者的角度，为公众关注的超声相关健康热点提供科学易懂的解释。内容涵盖人体头、颈、胸、腹等多个器官系统，涉及妇产科、男性、儿科常见疾病的超声诊疗应用，引导公众对超声医学有更多共识和认同。Ultrasound medicine, as the fastest developing, most penetrating, and most practical emerging discipline in modern medical imaging, has been widely used in clinical practice since the 1980s due to its advantages of convenience, accuracy, and non-invasive. With the in-depth research and development of acoustic physics technology and the rapid development of modern computer technology, ultrasound medicine has evolved from early one-dimensional ultrasound to real-time two-dimensional ultrasound, three-dimensional ultrasound, and color Doppler ultrasound, and even the emergence of the latest intelligent technologies such as real-time dynamic ultrasound contrast, ultrasound image fusion navigation, and interventional ultrasound. It has become a new type of medical imaging system that integrates clinical diagnosis and treatment functions. The creation of the book "Sound, Emotion, and Health Protection" aims to help more people understand the development and application of ultrasound medicine and its new technologies in clinical practice. This book introduces the origin, development, current situation, and prospects of ultrasound medicine to the public in simple and easy to understand language by ultrasound medical experts. At the same time, from the perspective of ultrasound medical workers, it provides scientific and easy to understand explanations of health hotspots related to ultrasound that the public is concerned about. The content covers multiple organ systems such as the head, neck, chest, and abdomen of the human body, and involves the application of ultrasound diagnosis and treatment for common diseases in obstetrics, gynecology, men, and pediatrics, In order to lead the public to have more consensus and identification with ultrasound medicine. </p>
