An algorithm was developed in this study, using rule-based fuzzy logic, to enable masses that are hard to recognize or detect in mammograms to become more readily perceptible. Small lesions, such as microcalcifications and other masses that are hard to recognize, especially on film scan mammograms, were processed through segmentation. A total of 40 mammograms were used and they were classified by radiologists into three groups: those with microcalcifications (n=15), those with tumours (n=15), and those with no lesions (n=10). Five mammograms were taken as training data sets from each of the groups with microcalcifications and tumours. The algorithm was then applied to data not taken for training. The algorithm achieved a mean accuracy of 99% compared with the findings of the radiologists.
本研究开发了一种算法,利用基于规则的模糊逻辑,使乳腺钼靶片中难以识别或检测到的肿块更容易被察觉。通过分割处理了小病灶,如微钙化和其他难以识别的肿块,尤其是在胶片扫描乳腺钼靶片上。总共使用了40张乳腺钼靶片,放射科医生将它们分为三组:有微钙化的(n=15)、有肿瘤的(n=15)和无病变的(n=10)。从有微钙化和肿瘤的每组中选取五张乳腺钼靶片作为训练数据集。然后将该算法应用于未用于训练的数据。与放射科医生的诊断结果相比,该算法的平均准确率达到了99%。
