Abstract: Intensity inhomogeneity caused by an ultrasonic attenuation beam within the body results in an artifact effect. It frequently degrades the boundary and texture information of a lesion in a breast sonogram. A new Gibbs-weighted K-means segmentation approach with intensity inhomogeneity correction is proposed to cluster the prominent components provided by fuzzy cell competition algorithm for segmenting lesion boundaries automatically with reducing the influence of the intensity inhomogeneity. The information of fuzzy C-means, normalized cut, and cell-based fuzzy cell competition algorithm are combined as the feature vector for cell-based clustering. 49 breast sonograms with intensity inhomogeneity, each from a different subject, are randomly selected for performance analysis. The mean distance between the lesion boundaries attained by the proposed algorithm and the corresponding manually delineated boundaries defined by two radiologists is 1.571±0.513 pixels. (Assessing Chan and Vese l evel set method for intensity inhomogeneity-correction segmentation in the same way, the mean distance error is3.299±1.203 pixels, for the 49 images.) The results show that Gibbs-weighted K-means segmentation approach with intensity inhomogeneity correction could not only correct the intensity inhomogeneity effect but also improve the segmentation results.
