Computer-aided Diagnosis of Breast Ultrasound Image Based on BI-RADS

Based on an standard classification(BI-RADS) used in breast ultrasound image,we design this computer-aided system.The lattice Boltzmann models is used here as an effective method to de-noise the speckle, also an improved CV models is adopted here,shape and texture features is both considered in extracting feature parameters. In the end support vector machines is used for classification.Experiments on 88 cases(including 37 benign tumors and 51 malignant ones) achieve the accuracy91.4%,sensitivity94.4%and specificity 86.4%.Therefore,the result proves that this method based on BI-RADS can be helpful for computer-aided diagnosis.
