儿童肺炎是一种严重威胁全球儿童健康的疾病,其精准分类是有效治疗的关键,但其X射线图像兼具细微病理纹理与大范围弥漫性病变,单一空间域模型难以高效协同表征。为此,本文提出融合空间域与多轴频域分析的儿童肺炎分类模型。模型前两阶段构建位移感知多尺度单元,捕捉细粒度病理纹理;后两阶段设计多轴傅里叶单元,在频域建模长距离依赖,刻画大范围病变特征。此外,设计多核卷积门控线性单元增强各阶段特征表示。实验表明,模型在ChestXRay2017数据集上,准确率和F1分数较最优对比模型分别提升2.72%和2.75%,并在VinDr-PCXR和Curated X-Ray数据集上均取得具有竞争力的性能。本文结果验证了模型的有效性与泛化性,为儿童肺炎诊断提供了新方案。
- Abstract:

Pediatric pneumonia poses a serious threat to children’s health worldwide, and its precise classification is crucial for effective treatment. Chest X-ray images used for pneumonia classification exhibit subtle pathological textures and large-scale diffuse lesions, making it difficult for a single spatial domain model to efficiently and effectively represent both characteristics. To address this issue, this paper proposes a classification model that fuses spatial domain and multi-axis frequency domain analysis. In the first two stages of the model, a shift-aware multi-scale unit is constructed to capture fine-grained pathological textures. In the last two stages, a multi-axis Fourier unit is constructed to model long-range dependencies in the frequency domain and characterize large-scale lesion features. Additionally, a multi-kernel convolutional gated linear unit is developed to enhance feature representation at each stage. Experimental results showed that on the ChestXRay2017 dataset, the model achieved improvements of 2.72% and 2.75% in accuracy and F1-score, respectively, compared to the state-of-the-art model. It also achieved competitive performance on the VinDr-PCXR and Curated X-Ray datasets, validating the model’s effectiveness and generalization. Thus, the proposed model provides a new solution for the auxiliary diagnosis of pediatric pneumonia.
