• With the aim of investigating possible improvements in visualization of carotid atherosclerotic plaque, a new dedicated off-line multi-angle ultrasound compound scanner has been built and tested on human tissues. Images were recorded from 7 insonification angles over a range of 42 degrees and the individual single-angle images were combined (averaged) into a single image (spatial compounding). This technique is denoted multiangle compound imaging (MACI). Compared to conventional B-mode imaging, this method features less angle-dependent images, since more scan lines are perpendicular (or nearly perpendicular) to the tissue interfaces. Further, the spatial compounding strongly diminishes the speckle pattern. These improvements are illustrated with in vitro images of human atherosclerotic plaque.
