超声很难对乳腺微钙化等小目标进行成像。合成孔径超声成像是近年来发展起来的一种改善医学超声性能的有前途的工具。我们使用两个不同的组织等效体模来研究实时合成孔径超声系统对小目标成像的能力。InnerVision超声系统DAS009是一种用于实时合成孔径超声成像的研究系统。我们使用该系统对这两个体模进行了成像，并与临床扫描仪Acuson Sequoia 512和西门子S2000获得的图像进行了比较。我们的结果表明，合成孔径超声成像比Acuson Sequoia 512和Siemens S2000产生的图像分辨率更高，伪影更少。此外，我们还研究了声速对合成孔径超声成像的影响，证明了准确的声速对小目标成像非常重要。
It is difficult for ultrasound to image small targets such as breast microcalcifications. Synthetic aperture ultrasound imaging has recently developed as a promising tool to improve the capabilities of medical ultrasound. We use two different tissueequivalent phantoms to study the imaging capabilities of a real-time synthetic aperture ultrasound system for imaging small targets. The InnerVision ultrasound system DAS009 is an investigational system for real-time synthetic aperture ultrasound imaging. We use the system to image the two phantoms, and compare the images with those obtained from clinical scanners Acuson Sequoia 512 and Siemens S2000. Our results show that synthetic aperture ultrasound imaging produces images with higher resolution and less image artifacts than Acuson Sequoia 512 and Siemens S2000. In addition, we study the effects of sound speed on synthetic aperture ultrasound imaging and demonstrate that an accurate sound speed is very important for imaging small targets.
