摘要:
肝包虫病是一种严重的地域性寄生虫病，其病灶分型主要依靠临床医生对超声图像的主观判断，疾病筛查工作中十分耗时，且容易造成误判．提出一种基于超声图像的肝包虫病病灶智能分型方法，首先从肝脏包虫病超声图像中直接裁剪得到病灶区域图像，利用深度卷积神经网络（convolutional neural network, CNN）提取图像多尺度特征，然后结合视觉注意力模型，通过分类网络的主分支和辅助分支分别学习图像的整体和局部细节特征，最后使用度量学习来表征同类别之间样本的相似特征，实现对9种类型的包虫病病灶进行全自动分类．构建了一个18层CNN网络，通过7 000张图像完成训练，在2 000张图像上测试得到的平均准确率为82%，平均F1分数为82%．实验结果充分表明，该方法能够有效应用于肝包虫病超声图像分型．
Abstract:
Hepatic echinococcosis is a serious regional parasitic disease, and its lesions classification mainly rely on the subjective judgment of clinicians on ultrasonic images, which is time-consuming and easy to cause misjudgment in disease screening. This study proposed an intelligent classification method for hepatic echinococcosis lesions based on ultrasound images. First of all, lesion images are cropped from the hepatic echinococcosis ultrasound images directly. The deep convolutional neural network (CNN) is used to extract multi-scale features. And then based on visual attention model, the main branch and the auxiliary branch of the classification network learn global image features and details local features, respectively. Finally, metric learning is used to measure the similarity of the samples in the same category. Automatic classification of nine types of echinococcosis lesions are realized. An 18-layer CNN network was constructed, and the training was completed with 7000 images. The average accuracy rate of the test on 2000 images was 82%, and the average F1 score was 82%. The results demonstrate that the proposed method can be effectively applied to the ultrasound image classification of hepatic echinococcosis.
