Abstract

The invention relates to an ultraphonic elastic imaging body model comprising polyacrylamide hydrogel and a scatterer, wherein the polyacrylamide hydrogel forms a reticular structure to wrap the scatterer. The elasticity (or the rigidity) of the ultraphonic elastic imaging body model can be freely regulated within a larger range by regulating the concentration of an acrylamide monomer and the sound attenuation coefficient can be changed to accord with the standard of ultraphonic elastic imaging by regulating the proportion of the scatterer.

Description

【Technical field】

[0001] The invention relates to the technical field of medical polymer materials, in particular to an ultrasonic elastography phantom and a preparation method thereof. 【Background technique】

[0002] There are many types of ultrasound elastography phantoms traditionally used, and they are mostly used for B-mode ultrasound imaging, image detection and correction of Doppler ultrasound imaging equipment, and skill training for doctors and technicians. In the development of instruments and clinical application of ultrasound elastography system, it is necessary to test the quality of the system, the most critical of which is to test the accuracy and reliability. The accuracy and reliability of the measured data are directly related to tissue characterization and the accuracy and reliability of disease diagnosis. Therefore, ultrasonic elastography cannot be used to test the elasticity (or hardness) of non-standard biological tissues as a standard for instrument ...
