Medical Image Report Generation Method Fusing Cross-View Features and Attention Mechanism

中文摘要英文摘要

目的 探索一种跨视角医学影像和医学报告对齐的策略,以优化深度学习模型自动生成医学影像报告的质量.方法 设计融合跨视角特征和注意力机制的生成模型,首先基于预训练模型编码不同角度拍摄的医学影像特征和报告病理描述特征;然后利用多种注意力机制完成特征的融合计算;最后利用解码器将联合特征解译成病例报告.结果 在权威公开的胸部X光数据集IU X-Ray上经过多轮测试可知,该模型在BLEU-1、BLEU-2、BLEU-3、BLEU-4、METEOR、ROUGE_L和P_MEAN评价指标上平均高于先前提出方法的8.34%、14.20%、10.90%、6.14%、1.70%、5.50%,综合性能提升7.79%.结论 该模型在生成报告的准确度和流畅度方面表现良好,说明该融合策略可以更好地捕捉影像和报告之间的潜在联系,提升模型生成报告的性能.

Objective To explore a cross-perspective strategy for aligning medical images and medical reports to optimize the quality of medical image reports automatically generated by deep learning models.Methods A generative model combining cross-view features and attention mechanism was designed.Firstly,different angles were taken by the medical image and the pathological description features of the report were encoded based on the pre-trained model.Then,multiple attention mechanisms were utilized to complete the fusion calculation of features.Finally,the joint features were decoded into case reports using the decoder.Results It could be known from multiple rounds of tests on the authoritative and publicly available chest X-Ray dataset IU X-ray that the average performance of this model in the evaluation metrics of BLEU-1,BLEU-2,BLEU-3,BLEU-4,METEOR,ROUGE_L and P_MEAN was higher than that of the previously proposed methods by 8.34%,14.20%,10.90%,6.14%,1.70%and 5.50%respectively,and the comprehensive performance was improved by 7.79%.Conclusion This model performs well in terms of the accuracy and fluency of report generation,indicating that this fusion strategy can better capture the potential connection between images and reports,and improve the performance of the model in generating reports.
