Introduction

The elastic modulus is an important mechanical characteristic of the material. The Young's modulus of human tissue is closely related to its physiological and pathological conditions The diagnosis of disease has important reference value. At present, based on ultrasonic pulse echo imaging platform for elastic imaging technology and equipment in the past decade To get the rapid development of clinical research has become a hot spot. As a new imaging technology, it extends the connotation of ultrasound diagnosis theory Ultrasound diagnosis range, make up for the lack of conventional ultrasound, so that modern ultrasound diagnostic technology is more perfect. Ultrasound elastography has a different implementation in technology. Taking into account the ultrasonic elastic imaging technology and equipment is still in development, this standard Only on the current relatively mature quasi-static ultrasonic strain elasticity imaging provides a technical test method, there is no provision for quantitative technical indicators parameter. The technical indicators for the methods proposed by this standard may not be available on some equipment. The users of this standard may choose Choose to use. Test method of ultrasonic quasi - static strain elasticity

1 Scope

This standard specifies the terms, definitions, test devices and the use of acoustic elastomeric molds for quasi-static ultrasonic strain elasticity imaging performance. method. This standard is applicable to quasi-static strain elastic imaging of human tissue using ultrasonic echo imaging.
