为了提高对比成像中的对比度与组织比(CTR)或组织谐波成像中的信噪比(SNR),已经提出了许多多脉冲传输技术。本文首先回顾了文献中提出的各种成像技术,然后提出了一个数学背景,以综合和推广大多数的多脉冲超声成像技术。提出的公式可以用来预测在每个频带中的非线性分量的相对幅度,并设计新的传输序列,以增加或减少指定的非线性分量在每个谐波带。几种多脉冲技术的模拟结果与以前的研究结果一致。
To increase the contrast-to-tissue ratio (CTR) in contrast imaging or the signal-to-noise ratio (SNR) in tissue harmonic imaging, many multipulse transmission techniques have been suggested. This article first recalls the various imaging techniques proposed in the literature and then presents a mathematical background to synthesize and generalize most of the multipulse ultrasound imaging techniques. The formulation presented can be used to predict the relative amplitude of the nonlinear components in each frequency band and to design new transmission sequences to either increase or decrease specified nonlinear components in each harmonic band. Simulation results on several multipulse techniques agree with the results from previous studies.
