Augmented reality system for assisting examinee to adapt to magnetic resonance scanning environment

Abstract

The invention discloses an augmented reality system for assisting an examinee to adapt to a magnetic resonance scanning environment, and the system comprises: positioning equipment which is used for providing position information; a virtual reality engine which is used for receiving the position information and presenting a virtual picture; eye movement and head movement acquisition equipment which is used for monitoring eye movement and head movement conditions of a subject in real time; and a biofeedback calculation system which is used for receiving the feedback condition of the eye movement and head movement acquisition equipment, automatically adjusting the virtual picture and automatically adjusting the closeness degree with the magnetic resonance environment according to the behavioral performance of the subject. By utilizing a biofeedback technology and an augmented reality technology, children, people with mild claustrophobia and mental disease patients gradually adapt to a magnetic resonance imaging environment, the retention time is prolonged, the anesthesia use frequency is reduced, the anxiety of children guardians is relieved, and the magnetic resonance scanning quality and the working efficiency are improved.

Description

technical field [0001] The invention belongs to the field of medical imaging, in particular to nuclear magnetic resonance imaging of the head (brain), and in particular to an augmented reality system for assisting a subject to adapt to the magnetic resonance scanning environment. Background technique [0002] Magnetic resonance imaging is one of the most commonly used means of medical imaging. When it is used for head (brain) examination, magnetic resonance imaging requires the examinee to keep his body still in the main magnetic resonance magnet during the scanning process, and it is required to keep still The time is usually 2-15 minutes. The space inside the magnetic resonance magnet is narrow, the light is dark, and the noise is very loud. In such an environment, children, people with claustrophobia, and patients with mental illness are usually difficult to meet the above requirements, resulting in low scanning success rate and poor image quality. question. In the exis...

Problems solved by technology

At present, the common practice of clinical examination is to anesthetize the examinee. Anesthesia has certain side effects, and some brain function tests (requiring the examinee to be conscious) cannot be realized.
