摘要

本研究的目的是开发六种斑点还原滤波技术，并结合纹理分析对240张颈动脉超声图像进行评估。该去斑点滤波器基于各向异性扩散、高矩局部统计和几何滤波。结果表明，去斑滤波后，图像的类别分离(症状斑块和无症状斑块之间)有明显改善。

Speckle reduction in ultrasound images of atherosclerotic carotid plaque

The objective of this work was to develop six speckle reduction-filtering techniques and evaluate them together with texture analysis in the assessment of 240 ultrasound images of the carotid artery. The de-speckled filters are based on anisotropic diffusion, local statistics with higher moments, and geometric filtering. Results showed that some improvement in class separation (between symptomatic and asymptomatic plaques) of the images was evident after de-speckle filtering.
