A multimodal information fusion system for esophagus functional disease diagnosis system

Abstract

The invention discloses a multi-modal information fusion system for esophageal functional disease diagnosis system, which is configured in a computer. The multi-modal information fusion system includes a single-mode information input layer connected step by step, a single-mode Information conditional probability calculation layer, multi-modal information fusion probability calculation layer and classification decision layer; each single-modal information conditional probability calculation unit is equipped with a corresponding Bayesian inference model, and the Bayesian inference model defines There are m kinds of functional diseases of the esophagus; the i-th Bayesian inference model is configured with m conditional probability tables, conditional probability table E ij The conditional probability that the jth esophageal functional disease is manifested as the i-th unimodal information is stored in ; the multimodal information fusion probability calculation layer is used to calculate the multimodal information fusion probability; the classification criterion layer is used for esophageal functional diseases Final category judgment. The invention can realize multimodal information fusion to diagnose esophageal functional diseases, and can improve the diagnostic accuracy.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multimodal information fusion system used in a diagnosis system for esophageal functional diseases. Background technique [0002] Functional esophageal disease refers to a type of esophageal disease whose clinical manifestations are symptoms in the esophagus or adjacent areas, and no organic lesions are found by biochemical, imaging, and endoscopic examinations, or the clinical symptoms cannot be explained by organic diseases . According to epidemiological statistics, the annual average incidence rate of esophageal functional diseases worldwide is 25%. In China, at least 200 million people have symptoms related to esophageal functional diseases, and the number of patients is increasing year by year. 50-60% of these patients need to receive accurate diagnosis and symptomatic treatment. The most typical esophageal functional diseases mainly include: (1) non-erosive gast...
