Abstract: In clinical diagnosis, metacarpal and phalangeal fractures are difficult to be detected and easy to be misdiagnosed. Therefore, an experimental study was carried out on accurate detection and location of the fractures in X-ray image. A computer-aided diagnosis(CAD)system based on deep learning was developed by improving the anchor frame, feature map generation and loss function of Faster R-CNN. The proposed CAD system greatly enhanced the network performance while saving computing power. 5195 X-ray images of hand were collected, of which 4675 were randomly selected as training set and 520 as test set. The experimental results show that the average precision of the proposed model in the test set is 69.3%. Compared with Faster R-CNN, the new framework can identify the location of metacarpal and phalangeal fractures more accurately, which verifies the potential clinical application value of the new model.- DOI:10.3969/j.issn.1000-1565.2021.04.011一种基于GA_Faster R-CNN的掌指骨骨折计算机辅助诊断系统杨昆^1,2,罗萍¹,吕一品¹,闫惟娜¹,吴海涛¹,刘爽^1,2,薛林雁^1,2(1.河北大学质量技术监督学院,河北保定 071002;2.河北大学计量仪器与系统国家地方联合工程研究中心,河北保定 071002)摘要:为解决临床掌指骨骨折诊断中难检测、易漏诊的问题,对如何更加准确地检测和定位X线图像中掌指骨骨折区域进行实验研究.开发了一种基于深度学习的计算机辅助诊断系统,改进了Faster R-CNN网络模型中的锚框、特征映射和损失函数,在节约算力的同时大大提高了网络性能.建立了包含5 195张手部的X线图像的数据集,其中随机抽取4 675张作为训练集,520张作为测试集.实验表明,提出的新模型在测试集上的平均精度达到了69.3%,与Faster R-CNN相比能够更加精准地识别出掌指骨骨折区域,验证了该模型具有潜在的临床应用价值.关键词:掌指骨骨折;Faster R-CNN;计算机辅助诊断;导向锚定中图分类号:TP391.7 文献标志码:A 文章编号:1000-1565(2021)04-0412-07A computer aided diagnosis system for metacarpal and phalangeal fracture based on GA_Faster R-CNNYANG Kun^1,2,LUO Ping¹,LYU Yipin¹,YAN Weina¹,WU Haitao¹,LIU Shuang^1,2,XUE Linyan^1,2(1.College of Quality and Technical Supervision, Hebei University, Baoding 071002, China; 2.National & Local Joint Engineering Research Center of Metrology Instrument and System, Hebei University, Baoding 071002, China)Abstract: In clinical diagnosis, metacarpal and phalangeal fractures are difficult to be detected and easy to be misdiagnosed.
