Emotional stability evaluation system and evaluation method based on magnetic resonance imaging

Abstract

The invention discloses an emotional stability evaluation system based on magnetic resonance imaging and an evaluation method thereof. The emotional stability evaluation system comprises an emotional stability characteristic sample database, a magnetic resonance imaging unit, a characteristic extraction unit, a pattern classifier and an emotional stability evaluation unit, wherein a magnetic resonance structure of emotional levels and emotional components with different emotional stabilities and resting state functional imaging attributes are stored in the emotional stability characteristic sample database; the magnetic resonance imaging unit acquires imaging data of a magnetic resonance structure phase and a resting state functional phase of the brain of a detected individual, and transmits the imaging data to the characteristic extraction unit; the characteristic extraction unit extracts the magnetic resonance structure and the resting state functional imaging attribute of the brainof the detected individual from the imaging data; the pattern classifier carries out classifier training on the magnetic resonance structure and the resting state functional imaging attribute; and the emotional stability evaluation unit evaluates the emotional stability level and / or emotional cause of the detected individual according to the classifier training result, the magnetic resonance structure and the resting state functional imaging attribute. Therefore, the system realizes accurate, objective and stable evaluation on the emotional level and cause of the detected individual.

Description

technical field [0001] The invention relates to the medical field, in particular to a magnetic resonance imaging-based emotional stability evaluation system and an evaluation method thereof. Background technique [0002] Emotion is a comprehensive psychological and physiological state of people's various feelings, thoughts and behaviors. It is a psychological reaction to external stimuli, as well as accompanying physiological reactions, such as: joy, anger, sadness, joy, etc. Emotions are personal subjective experiences and feelings, often related to mood, temperament, personality and temperament. Emotion is the external phenotype of mental activity, and this external phenotype is more likely to be manifested when the individual is in a stressful situation. [0003] Emotional stability means that the individual does not show excessively excited reactions in emotional situations, and it is the embodiment of the individual's emotional self-regulation ability and a sign of per...

Problems solved by technology

[0011] However, the existing subjective evaluation methods for evaluating emotional stability are easily affected by many external factors, thereby affecting the objectivity and accuracy of the evaluation. The existing objective evaluation methods only rely on a single index to judge and cannot accurately and objectively reflect the emotional stability. Moreover, the existing evaluation methods mainly focus on the strength of emotional stability, and cannot distinguish the psychological and emotional factors in the emotional state.

[0012] In summary, the existing emotion evaluation technology obviously has inconvenience and defects in actual use, so it is necessary to improve it
