Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. Please note that some of the contents of this document may involve patents. The issuer of this document does not assume responsibility for the identification of these patents. This standard is proposed by the State Food and Drug Administration. This standard by the National Medical Electrical Standardization Technical Committee of medical ultrasound equipment standardization sub-technical committee (SAC/TC10/SC2) Go back. The standard drafting unit. the key technology of medical ultrasound national joint engineering laboratory, the State Food and Drug Administration Hubei Medical Equipment Quality Supervision and Inspection Center. The main drafters of this standard. Chen Siping, Chen Xin, Jiang Yilin, Xuanyuan Kai. Performance of Ultrasonic Elastic Imaging Equipment Based on Acoustic Radiation experiment method

1 Scope

This standard specifies the term, definition, and definition of the performance of ultrasonic elastic imaging equipment based on acoustic radiation using ultrasonic elastic imitation of tissue molds, Test equipment and test methods. This standard applies to the use of ultrasonic echo imaging principle of human tissue elastic imaging equipment, the device of the type of force is the use of ultrasound The resulting focusing radiation force, the measured elasticity parameter, can be either a displacement or a shear wave velocity (or a shear wave velocity converted by the formula Modulus), the display can be measured or imaging. A reference classification of the Ultimate Elastic Imaging System is given in Appendix A, and the scope of application of this standard is the acoustic radiation pulse imaging in the appendix, Point shear wave elastic imaging, shear wave elasticity imaging
