Problems solved by technology

In recent years, there has been remarkable progress in the research of brain power imaging technology that can be used for cognitive learning and dysfunction of children with autism at home and abroad. However, most of the existing brain-derived imaging technologies are based on the minimum norm method, with limited degrees of freedom and the complexity of human brain-derived activities. Strong and high-resolution requirements lead to low accuracy of brain power imaging for cognitive learning and dysfunction in children with autism

Abstract

The invention discloses a Bayesian-based imaging system for abnormal lesion areas of children's brain activity. The system includes: a signal processing module, used to obtain brain electromagnetic sampling data, and preprocess the electromagnetic sampling data; an abnormal brain activity identification module, used to identify abnormal waves and non-abnormal waves from the preprocessed brain electromagnetic sampling data The noise estimation module is used to estimate the background interference noise from the non-abnormal wave; the brain source activity reconstruction module is used to combine the abnormal wave and the estimated background interference noise, and use the Bayesian estimation method to obtain the location of the brain abnormal activity lesion and The time series of brain-derived activity in the lesion area; the imaging module is used for imaging according to the brain-derived activity. The invention can greatly improve the accuracy of locating and reconstructing the lesion area, and is especially suitable for imaging the lesion area of ​​abnormal brain electrical activity of children with autism.

Description

technical field [0001] The invention belongs to the technical field of reconstruction of brain lesion areas of children with autism, and more specifically relates to a Bayesian-based imaging system for abnormal brain activity lesion areas of children. Background technique [0002] As the most important part of the central nervous system, the brain controls people's advanced thinking, such as cognition, learning, and social interaction. The education of children with autism and the intervention and treatment of brain dysfunction first need to understand the cognitive learning of children with autism. Processes and mechanisms of brain function in brain dysfunction. Brain power imaging is an important means to explore the mechanism of brain activity, understand various thoughts and perceive the dynamic changes in brain activity, and it is of great significance to reveal the brain operation mechanism of children with autism. [0003] The inverse problem of brain power imaging i...
