Abstract

In this study, the examination results of speed of sound of sliced rat organs analyzed with multi-frequency ultrasound (80 and 250 MHz) from the acquiring radiofrequency (RF) echo signals observed by our self-made scanning acoustic microscopy (SAM) system is reported. The frequency dependence of SoS was evaluated by analysis method involving filtering considering spatial resolution at each frequency.
