| Abstract(in English) | It is known that the ultrasound integrated backscatter(IB)from heart wall shows the cyclic variation during a cardiac cycle. In this study, by measuring the IB from the heart walls of two human healthy subjects and a rabbit at a high pulse repeatation frequency, the rapid variation in the IB signal was detected. In the phase that the speed of change in thickness was large, the period of rapid variation was short. We assume that the period of the rapid variation in the IB signal has a close relationship with the regional change in thickness of heart wall. |
