The LER technique provides highly accurate and robust automated measurements of carotid intima-media thickness compared to manual assessment and other automated techniques.
This paper reports three techniques for automated intima–media thickness measurement in the B-mode common carotid artery ultrasound images. These are the gradient based (GB), localising region-based active contour (LAC) and level-set evolution without re-initialisation (LER). Authors have reported results with quantitative and qualitative comparisons. From results, it is observed that the performance of LER is superior in terms of accuracy and robustness in the presence of weak boundaries and strong noise. The correlation coefficients between automated measurements and manually obtained reference values were 0.63, 0.76 and 0.98 for GB, LAC and LER techniques, respectively (N = 66). The figure-of-merit of LER was 99.59%, better than GB (88.86%) and LAC (98.52%).
