Scope

This Standard specifies the requirements, test conditions and test methods of external-
vibration based ultrasonic elasticity measurement equipment for liver tissue
(hereinafter referred to as the equipment).
This Standard is applicable to equipment that excites shear waves in liver tissue by
externally applying low-frequency vibration and uses the ultrasonic pulse-echo mode
to measure the elasticity of liver tissue.
NOTE: the external-vibration based ultrasonic elasticity measurement technology for liver
tissue, to which, this Standard is applicable, corresponds to the instantaneous
elasticity image in the classification of ultrasound elastography. The classification
of the ultrasound elastography is shown in Appendix A.
