Abstract

The invention provides a method and a device for establishing an age prediction model, an age prediction method and a device. The method comprises: building m references on the x-axis, y-axis, z-axisData sets (described in the description) corresponding to T1-weighted images of brain slices in each slice direction and T<n><n>(z, g), where w refers to the white matter T1-weighted image corresponding to the white matter region and g refers to the grey matter T1-weighted image corresponding to the grey matter region; n is the number of the reference person and n has a value ranging from 1 to m.According to the true age of the reference person corresponding to the T1-weighted image, age identification is added to the T1-weighted image in each data set. Convolution-based neural network pairdata sets (described in the description) and T<n><n>(z, g), corresponding data sets (described in the description)and <n><n>(z, g) are established. The age predictor model with the highest precision of age prediction is selected as the age predictor model.

Description

technical field [0001] The invention relates to the technical fields of medical image processing and computer vision detection, in particular to a method and device for establishing an age prediction model, and an age prediction method and device. Background technique [0002] With the rapid development of human society, health problems have become the focus of people's attention, especially for the health problems of the elderly. Alzheimer's Disease (AD), commonly known as senile dementia, is one of the diseases that the elderly are most concerned about. Its clinical manifestations are language impairment and memory loss. [0003] Scientific research has found that Alzheimer's disease has a certain relationship with the atrophy of brain tissue. Currently, researchers analyze the MRI images of the patient's brain to predict the patient's brain age. If the predicted brain age is consistent with the actual The greater the age deviation, the greater the degree of brain atrophy...
