摘要

组织谐波成像可以得到精细的图像,对其采用脉冲压缩技术,还可以实现高信噪比的成像。为了实现最佳的脉冲压缩,重要的是要准备和使用合适的模板波形。然而,由于回波信号中的组织谐波成分具有复杂的特征,因此很难完全了解这种模板。在本研究中,我们实验研究了用于谐波脉冲压缩成像的模板波形与压缩波形之间的关系。

P3B-7 Study on Harmonic Pulse Compression Imaging with Consideration of Harmonic Property
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.
