本文提出了一种高质量超声应变图像形成的新方法。为了实现这一目标，通过自动性能评估方法选择三个射频回波帧，并用于生成位于相同物理网格中的两个母应变图像，可以通过求平均值来计算高质量的复合应变图像。自动性能评估方法将两个母应变图像之间的一致性和运动跟踪的准确性结合到单个概括的“位移质量度量”中。“所提出的算法是用从体内乳腺组织数据中获得的数据集进行评估的。我们的研究结果表明，所提出的应变形成方法显示出很大的潜力，优于文献中的其他方法。
This paper presents a new method for forming high-quality ultrasonic strain images. To achieve this goal, three radiofrequency echo frames are selected by an automated performance assessment method and used to generate two parent strain images located in the same physical grid from which a high quality composite strain image may be calculated by averaging. The automatic performance evaluation method combines the consistency among the two parent strain images and the accuracy of motion tracking into a single summary "displacement quality measure." The proposed algorithm is evaluated with datasets acquired from in vivo breast tissue data. Our results show that that the proposed strain formation method shows substantial potential to outperform other methods available in the literature.
