研究目的: |
基于已构建的多模态大模型,进一步融合临床、影像学指标、关键生物标志物和引入可学习的门控机制,实现三模态融合,并通过监督微调实现迁移学习,建立科学、全面的牙周病诊断分型指标体系。开发具有高度临床实用性的牙周病人工智能多模态融合诊断模型,实现牙周病自动识别与精准分期分级。在外部数据集验证诊断模型,完成真实世界验证。 |

Objectives of Study: |
Based on the established multimodal large model, we further integrate clinical indicators, imaging parameters and key biomarkers, and introduce learnable gating mechanisms to achieve trimodal fusion. Through supervised fine-tuning for transfer learning, a scientific and comprehensive indicator system for the diagnosis and classification of periodontal diseases is constructed. We develop a clinically practical AI multimodal fusion diagnostic model for periodontal diseases to realize automatic identification and accurate staging and grading of periodontal lesions. The model is validated on external datasets and verified in real-world clinical settings. |
