摘要
乳腺肿瘤边界特征量如似圆度,面积比率,边界粗糙度、长宽比等,是鉴别良、恶性肿瘤的重要特征。利用灰色理论中的待诊病例与良性、恶性肿瘤的关联度的阀值,即可判断出是良性还是恶性肿瘤。实验表明,在76幅待诊病例中,良性肿瘤识别正确率达到87.5%,恶性肿瘤识别正确率达到75%。该方法较为有效地识别良性、恶性乳腺肿瘤。
Parameters for margin features of breast tumor such as circularity,area ratio,contour roughness,length width ratio are the important characteristics to identify the benign or malignant tumor.The purpose of this article is to perform the diagnosis based on grey relation between the cases that to be diagnosed and benign or malignant tumor.Results from 76 ultrasonic images have shown that the identification accuracy of benign or malignant tumor are 87.5% and75% respectively.The methods applied in this paper can make an effective diagnosis for breast tumor.
