Preface

Ultrasound medicine refers to a non-invasive examination that uses the characteristics of ultrasound and the different principles of human tissue reflection on ultrasound to form images to diagnose the morphological structure, physical characteristics, functional status and pathological status of human tissue.
     Ultrasound medical diagnosis is widely used in clinical applications, with simple operation, convenient use, cost-effective, high accuracy, good localization, and high diagnosis rate of patients’ complications. Therefore, its clinical application is more extensive, providing the valuable reference information, and it can make a treatment plan in time and improve the success rate of first aid, especially in the diagnosis of some abdominal trauma and acute abdomen.It has a great effect on the development of the emergency medical system, which is recommended to provide this kind of diagnostic method for emergency patients in the clinic to improve the diagnosis accuracy of patients and improve treatment effect.
      Combined with the current social development status, this book introduces the related theories and knowledge of ultrasound medicine in many aspects, focusing on the current imaging research. The contents of the book are comprehensive, systematic and practical. It is s also suitable for teachers and students of medical imaging major in colleges and universities, and engineering and technical personnel engaged in ultrasound instrument sales, application training and hospital equipment management to learn and refer to.

前 言

超声医学是指应用超声波的特性和人体组织对超声反射不同的原理形成图像，来诊断人体组织的形态结构、物理特征和功能状态及病理状态的一种非创伤性检查。
  超声医学诊断临床应用广泛，其操作简单，使用便捷，性价比高，准确率高，定位性好，对患者的并发症也有较高的诊出率， 因此临床应用比较广泛，为临床诊断提供了有价值的参考信息，可以及时的制定治疗方案， 提高急救成功率。尤其是在一些腹部创伤和急腹症的诊断中效果突出，对于急救医疗体系的发展提供了较大的帮助，建议在临床中为急诊患者提供该种诊断方式， 提升患者的诊断准确率， 提升治疗效果。
  本书结合当前社会发展现状，从多个方面详细介绍了超声医学相关理论与知识，其中重点包含目前影像研究相关内容等。书中内容全面、系统、实用，亦适合大专院校医学影专业的师生，从事超声仪器销售、应用培训及医院设备管理的工程技术人员学习、参考。
