Camera-based transcranial magnetic stimulation diagnosis head model building system

Abstract

A camera-based transcranial magnetic stimulation diagnosis head model building system is disclosed, including a 3D scanner, a positioning hat and an intelligent terminal, wherein the 3D scanner and the intelligent terminal are electrically connected. A model building method of the system includes collecting 3D image data of a head of a patient from all directions through cameras, and integrating the image data to obtain complete 3D image data; through combining MNI brain space coordinates, mapping a skull model obtained by MNI spatial 3D brain scanning to the 3D head model data of the patientto obtain a head model matching the actual head height of the patient, thus increasing the precision of subsequent positioning of transcranial magnetic stimulation points for the head of the patient,and further greatly improving TMS magnetic stimulation treatment effects. The head model of the patient can be obtained only by steps of collecting 3D head data of the patient through the 3D cameras and processing the collected data through the intelligent terminal in the system. The system is cheap, simple to operate and high in degree of automation.

Description

technical field [0001] The invention belongs to the technical field of transcranial magnetic stimulation medical technology, in particular to a head model modeling system for transcranial magnetic stimulation diagnosis and treatment based on a camera. Background technique [0002] According to statistics from the Mental Health Center of the Chinese Center for Disease Control and Prevention, the total number of mental illness patients in my country has exceeded 100 million, but the public awareness rate of mental illness is less than 50%, and the rate of seeing a doctor is even lower. At present, about 20% of these mental patients receive timely treatment, and 80% of the mental patients do not receive timely treatment, or even the most basic treatment. The number of mentally ill patients is as high as 16 million. According to the latest statistics from IMS health, the global psychiatric drugs have exceeded 36 billion US dollars, accounting for 5% of the total drug sales. How...

Problems solved by technology

The modeling system of the present invention is low in cost, strong in automation, does not require too much manual operation, and has a high degree of fit between the constructed head and the patient's own head, which can effectively improve the positioning accuracy of the subsequent magnetic stimulation points. Thereby improving the treatment effect; the headform modeling method of the present invention solves the problem that the headform does not match the patient's head caused by the software headform in the prior art, thereby reducing the problem of stimulating treatment effect; it also solves the problem that the current In the existing technology, based on the anisotropic conductivity head model and the comprehensive index of individual cortical excitability, the construction of an anisotropic conductivity head model containing cortical excitability is a problem of high cost and high operational difficulty.
