Abstract

Shear wave Imaging is a technique that estimates tissue stiffness by measuring shear wave induced by Push Beam. However, a decay of estimate accuracy may accrue due to motions of such as pulsation and breathing. In this presentation, we propose estimation method of tissue stiffness based on the pulse propagation.Verasonic and 7.5 MHz Linear Probe were utilized to acquire raw data. The frame rate was 1 kfps. The identical data was used to measure the velocity by a modified 1D-cross-correlation-algorithm. A measurement area was right common carotid artery of 24-year-old healthy male.The pulse propagation was visualized with high-frame-rate ultrasound imaging. The dispersion-relation was observed. For example, the velocity of artery was 6.08 ± 0.19 m/s, and that of muscle was 7.43 ± 0.30 m/s at 15 Hz. It was possible to visualize the appearance of propagation induced by pulsation. The dispersion relation was revealed by the proposal method.
