Abstract

The invention discloses a children autism spectrum disorder analysis system based on near-infrared brain imaging map features. The steps of the system are listed as follows: step one, the resting state near-infrared brain imaging data of a large number of normal children and autism spectrum disorder children are acquired through an annular near-infrared brain imaging acquisition scheme; step two,the phase synchronization coefficient of the hemoglobin change level time sequences of any two channels is calculated and a synchronization network is established; step three, the network feature parameters of the complex network of the two groups of the normal children and the autism spectrum disorder children are calculated and then a training data sample set and a test sample set are acquired;step four, pattern classifiers are acquired for the training data sample set and the test sample set of the two groups of the normal children and the autism spectrum disorder children according to thestandard forward neural network structure design technology; and step five, the diagnosis result of the risk of children autism spectrum disorder is finally realized by using the pattern classifiersacquired in the step four.

Description

technical field

[0001] The invention relates to an analysis system for children with autism spectrum disorder based on near-infrared brain imaging spectrum features, and belongs to the technical field of medical diagnosis. Background technique

[0002] Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders characterized by social impairment, language communication impairment, narrow range of interests or activities, and repetitive stereotyped behaviors. ASD has become a serious challenge in the field of public health and education in the world. It seriously endangers children's physical and mental health. If it cannot be recovered, it can cause lifelong disabilities, affect the patient's lifelong physical and mental health, social interaction, study, life, and employment, and bring harm to the family and society. caused a serious burden.

[0003] Unraveling the neurodevelopmental characteristics of children with ASD presents a great challenge because: fir...
