医学超声中的二次谐波产生是由组织或超声造影剂引起的。传统的信号处理技术不能将微泡和组织的谐波响应分离出来。二阶谱分析，通常称为频率分析，是评估微泡响应的最常用方法。虽然频率分析可以有效地估计功率谱，但它抑制了频率分量之间的相位关系。在这项研究中，双谱分析被用来评估微泡响应和分离的二次谐波产生的组织和微泡通过基波和谐波分量之间的相位耦合。
The second harmonic generation in medical ultrasound is either caused by tissue or ultrasound contrast agents. The conventional signal processing techniques cannot separate the harmonic response from microbubbles and tissue. The second order spectral analysis, commonly known as the frequency analysis, is the most common way of evaluating the microbubble response. Although frequency analysis can estimate the power spectrum effectively, it suppresses the phase relation between the frequency components. In this study, bispectral analysis is used to evaluate the microbubble response and separate the second harmonic generated by tissue and microbubbles via the phase coupling between fundamental and harmonic components.
