A decision support system has been developed to assist the radiologist during mammogram classification. In this paper, mass identification and segmentation methods are discussed in brief Fuzzy region-growing techniques are applied to effectively segment the tumour candidate from surrounding breast tissue. Boundary extraction is implemented using a unit vector rotating about the mass core. The focus of this work is on the feature extraction and classification processes. Important information relating to the malignancy of a mass may be derived from its morphological properties. Mass shape and boundary roughness are primary features used in this research to discriminate between the two types of lesions. A subset from thirteen shape descriptors is input to a binary decision tree classifier that provides a final diagnosis of tumour malignancy. Features that combine to produce the most accurate result in distinguishing between malignant and benign lesions include: spiculation index, zero crossings, boundary roughness index and area-to-perimeter ratio. Using this method, a classification result of high sensitivity and specificity is achieved, with false-positive and false-negative rates of 9.3% and 0% respectively. |
