Problems solved by technology

At present, many companies have provided audio-visual stimulation device products, but the traditional visual stimulation device can only provide graphic stimulation in the 2D plane, the stimulation mode is relatively single, and cannot provide a more realistic visual stimulation environment, so it is difficult to obtain in the real environment. Functional activation images of human brain regions, limiting fMRI findings

Abstract

The invention discloses a virtual reality stimulation device for functional magnetic resonance imaging, comprising a virtual visual presentation assembly, an auditory presentation assembly, a motion detection feedback assembly, and a motion control assembly. By using the device, presentation of a large-field angle virtual environment can be effectively realized; in coordination with the motion detection feedback assembly, interaction such as viewing angle rotation and motion control between a subject and the virtual environment can be achieved; and a virtual environment scenario as much close to the reality as possible is provided so that a brain activity fMRI experimental result closer to the real environment can be obtained.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a virtual reality stimulation device for functional magnetic resonance imaging. Background technique [0002] Functional magnetic resonance imaging (fMRI) is an imaging technique that can be used to measure the functional activation of brain regions, and has been widely used in neurology and psychology research. When a person receives various external stimuli, corresponding brain regions will be activated in the brain, and different external stimuli will generate different activated brain regions. fMRI is mainly used to detect the position of various functional areas in the brain and the degree of response to various stimuli; before surgery that may involve brain functional areas, fMRI technology can be used to know in advance whether the corresponding functional areas will be damaged. At the same time, fMRI technology is also one of the most important methods for no...
