Ultrasound Imaging and Elastography

Ultrasounds have been used widely in medicine and devices which using acoustic waves have been giving more and more information in medicine. We propose the solution that based on phase analysis of acoustic wave packet in medicine diagnosis of soft tissue tumor. The aim of these investigations has been a construction of such a device and algorithm that would enable to find new diagnostic applications. Experimental results of 2D visualization of phase relations between acoustics fields are presented. For ~1.5MHz frequency ultrasound signal, the proposed method could measure phase relations with resolution ~0.05 rad.
