Abstract

Tissue harmonic imaging can get fine images, and by adopting pulse compression technique to it, imaging with high signal-to-noise ratio can be realized besides. In order to achieve optimal pulse compression, it is important to prepare and use a suitable template waveform. However, since tissue harmonic component in echo signal has complicated characteristics, such the template is difficult to be completely known. In this study, we investigate the relationship between template waveforms used in harmonic pulse compression imaging and compressed waveforms experimentally.
