Preface

In recent years, the application of ultrasound in medicine has been developing rapidly. Ultrasound diagnosis, with its simple, injury-free, pain-free, high accuracy and good repeatability, has been generally welcomed by clinicians and patients, and has become one of the most commonly used methods to diagnose diseases. With the development of ultrasound technology and ultrasonic instruments, ultrasound medicine has become more and more widely used, and has gradually become an important content that ultrasound medical workers must learn.

  Ultrasound medicine is a diagnostic method of ultrasound comprehensive imaging, which is a highly theoretical and practical subject, and is widely used in clinical medicine. It not only involves general internal surgery, obstetrics and gynecology, pediatrics and other major departments, but also has close contact with many specialties such as neurology, cardiovascular, urology, endocrinology, oncology, etc. With the increasing scope of clinical application of ultrasound imaging technology, in order to facilitate medical personnel to learn and use ultrasound diagnosis and treatment technology, we compiled this book on the basis of a large number of domestic and foreign literature.

  The Editorial Board Members of this book has grasped the principle of “less and more refined” and simplified as far as possible. Due to the limitation of space and the level of the editor, there are inevitably some omissions and improperieties in the content of this book, readers are welcome to criticize or correct them.

前 言

近年来，超声在医学上的应用得到了飞速的发展。超声诊断以其简便易行、无损伤、无痛苦、准确性高、重复性好等特点，受到临床医生和患者的普遍欢迎，成为诊断疾病最常用的方法之一。超声技术和超声仪器的发展进步，更使得超声医学拥有了愈加广阔的应用领城，逐渐成为超声医学工作者必须学习的重要内容。
      超声医学是超声综合成像技术用于临床的诊断方法，是理论性和实践性很强的学科，在临床医学中的应用越来越广泛。它不仅涉及一般内外科、妇产科、儿科等主要科室，还与不少专科如神经内科、心血管科、泌尿外科、内分泌科、肿瘤科等有着密切联系。随着超声影像技术临床应用范围的日益扩大，为了便于医务人员学习和运用超声诊断和治疗技术， 我们在参考了大量国内外文献的基础上编写了此书。
       本书编委们掌握尽可能“少而精”和删繁就简的原则，由于篇幅限制和编著者的水平，本书内容难免尚有疏漏、不当之处，诚恳希望同道们不吝指正。
