Abstract
This paper presents developed radiofrequency (RF) ultrasound based strain elastography imaging method, which operates and could be adjusted in frequency domain. The method was verified by using agar-based tissue mimicking substitute. The phantom had 7 kPa stiffness background material and two inclusions of different stiffness 15 and 30 kPa. The displacements in the phantom material were induced by hand. The obtained strain contrast-to-noise ratio between the background material and two inclusions is 1.32 and 1.50 respectively. These results confirm the differentiation power of the method characterizing relative elasticity in-vitro.
