摘要

在过去的几十年里,合成孔径聚焦方法在多个研究领域做出了巨大的贡献。它们中的大多数试图以增加计算复杂度为代价来平衡图像质量。本文提出了一种改进的方法,该方法在最简单的合成孔径聚焦时域法获得的速度和重建聚焦孔径投影的精度之间达到一个中点。在建议的方法中还描述了关于实施半自动或自动检查系统的细节。最后,在评估结果部分,建议的方法探测到能够成像小到大约0.035 mm的小特征。

Ultrasound high resolution imaging using a modified synthetic aperture focusing method
Over the last decades, large contributions have been made to Synthetic Aperture Focusing methods in multiple areas of research. Most of them try to balance the image quality at expense of increasing the computational complexity. In this paper, a modified method is presented, in which a midpoint is reached in between the accuracy of recreating focused aperture projections and the speed obtained by using the simplest Synthetic Aperture Focusing time-domain method. Details regarding the implementation of focusing on semi-automatic or automatic inspections systems are also described in the proposed methodology. Finally, in the evaluation results section, the suggested approach probes to be able to image small signatures up to approximately 0.035 mm.
