AI Technical Summary

Technical Problem

Existing technologies have limitations in the fusion processing of multimodal images in the diagnosis of oral diseases. They cannot achieve precise segmentation and identification of teeth and soft tissues, or three-dimensional reconstruction. They are also difficult to accurately identify the boundaries of inflammatory lesions, and the spatial positional deviation between images has not been resolved.

Method used

An intelligent auxiliary diagnostic system for oral diseases using multimodal imaging is employed. Through data reception, image analysis, multimodal fusion, and intelligent diagnostic modules, it achieves automatic delineation and segmentation of teeth and soft tissues, three-dimensional reconstruction and feature fusion, generating a unified multimodal fused oral digital model, and performing disease type listing and quantitative assessment.

Benefits of technology

It achieves a clear correspondence between tooth location and soft tissue boundaries, detailed reconstruction of bone density distribution and root canal structure, accurate identification of inflammatory lesion boundaries, and construction of a unified multimodal fusion oral digital model, thereby improving the comprehensiveness and relevance of disease diagnosis.

Abstract

The invention relates to the technical field of oral medical image intelligent diagnosis, in particular to an oral disease intelligent auxiliary diagnosis system fused with multi-modal images, which comprises a data receiving module for receiving intraoral optical photos, cone beam CT (computed tomography) and oral maxillofacial MRI (magnetic resonance imaging); the image analysis module automatically draws and segments the optical photo to generate a two-dimensional structure chart with a tooth position identifier, reconstructs a three-dimensional jaw bone for CBCT, extracts a root canal structure to generate a model containing bone density and root canal parameters, enhances soft tissue for MRI, identifies an inflammatory region and generates a model showing muscle vascular nerves and inflammatory boundaries; the multi-modal fusion module constructs a unified digital model through space registration and feature fusion; and the intelligent diagnosis module calls the pre-training model for analysis and reasoning, and generates a disease list and quantitative parameters. According to the system, through differential image processing and multi-modal fusion, oral cavity structure and lesion panorama presentation is realized, and disease recognition comprehensiveness is enhanced. According to the invention, the accuracy and efficiency of intelligent auxiliary diagnosis of oral diseases can be improved.
