| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have implemented this study by evaluating the effect of two things on ultrasound imaging. The first one is proposing the different way of calculating the steering vector that is used for Super-resolution FM-Chirp correlation Method (SCM) afterward. This steering vector is generated by some echoes from some points with different depths around the focal point measured in advance and by interpolating them subsequently. Moreover, we decide to call this method Adaptive SCM. The second one is applying Harmonic whose frequency has several times than the original wave to SCM, instead of the fundamental frequency. Besides that, we also implement according to the original way that uses conventional steering vector and fundamental frequency signals. We show both simulation and experimental results to compare and evaluate the possibility of proposed methods. | |
