摘要
现代超声诊断已经广泛应用彩色多普勒血流成像、谐波成像、造影成像、三维成像等很多新技术。声像图诊断和超声断层扫描技术是现代超声的主体,声像图即超声断层图,可反映人体断面解剖结构。医学超声领域涉及的基本概念、数学物理基础众多,如超声换能器及其声场的产生、生物组织的基本声参量、超声的成像原理、超声多普勒效应、声波的声特性等。对这些应用于检验检测方面的医用超声基础的详细了解和掌握,对增强检验检测能力,提高检验检测效率起到了重要的作用。文章是对医学超声基础在检验检测领域的应用价值研究方面的深入探讨。
The basis of ultrasonic diagnosis is that the propagation rule and wave phenomenon of ultrasonic such as penetration,reflection and scattering are also different due to the difference of ultrasonic propagation,tissue characteristics and geometric dimensions in biological tissues,so that the parameters such as amplitude,frequency,phase and time of the received signal are changed differently.The difference of tissue and tissue can be identified through the measurement and imaging of these parameters Pathological characteristics.the field of medical ultrasound involves many basic concepts,mathematical and physical foundations,such as the generation of ultrasonic transducer and its sound field,the basic acoustic parameters of biological tissue,the imaging principle of ultrasound,ultrasonic Doppler imaging,acoustic characteristics of sound,etc.The detailed understanding and mastering of the medical ultrasonic foundation applied in inspection and detection plays an important role in enhancing the inspection and detection ability and improving the inspection and detection efficiency.This paper is an in-depth study on the application value of medical ultrasound in the field of inspection and detection.
