Sinus sigmoideus blow flow model structuring method and device

Abstract

The embodiment of the invention discloses a sinus sigmoideus blow flow model structuring method and device. The method comprises, according to the medical image of a sinus sigmoideus structure, determining a sinus sigmoideus three-dimensional profile and establishing a sinus sigmoideus structure model; according to the medical image of sinus sigmoideus blood flow, obtaining haemodynamic parameters of a sinus sigmoideus internal flow field; according to the haemodynamic parameters of the sinus sigmoideus internal flow field, pumping corresponding simulated blood fluid medium into the sinus sigmoideus model. The sinus sigmoideus blow flow model structuring method solves the technical problem of how to break through the bottleneck due to experimental limitation and to establish high-simulation ear blood vessel flow models for providing accurate experimental data for exploring pathogenesis of vascular tinnitus.

Description

technical field [0001] The invention belongs to the field of medical models, in particular to a method and device for constructing a sigmoid sinus blood flow model. Background technique [0002] Vascular tinnitus is a common symptom of otology and neurology. There are about 9 million patients in my country, and the number is increasing year by year. Long-term tinnitus can seriously affect the patient's quality of life and work ability, and even cause serious consequences such as mental disorders (depression, irritability, etc.), suicide, etc., causing a great economic and social burden to the society. [0003] At present, the bottleneck in exploring the mechanism of vascular tinnitus, a common disease, is the lack of high-simulation experimental models for verification. In the human and animal experimental models, it is impossible to design different experimental conditions according to the requirements for multiple factors, and some experiments may pose a hazard to the hea...

AI Technical Summary

Problems solved by technology

In the human and animal experimental models, it is impossible to design different experimental conditions according to the requirements for multiple factors, and some experiments may pose a hazard to the health of the research subjects. In addition, due to the obstacles in the experimental research It directly affects the in-depth research on the pathogenesis of vascular tinnitus, and the experimental research on vascular tinnitus at home and abroad is limited to the anatomical structure of temporal bone, blood vessels and ear organs
