| Abstract(in English) | Integrated backscatter from heart wall is getting attention as a quantitative tissue characterization method. First, we reduced slowly time-varying artifact component from RF signal and then measured ultrasonic integrated backscatter in the same site of the heart wall at each time by improving time resolution and spatial resolution in the axial direction. As a result, we found that cyclic variations were different site by site. Next, we calculated interference cycle of IB signal and estimated velocity of change in thickness. According to the results, rate of change in thickness manually estimated by using interference cycle was in good agreement with that estimated by using the phase tracking method. These results show the possibility to estimate the rate of change in thickness by using IB signal. |
