Embodiment Construction
[0031] The present invention is further analyzed below in conjunction with specific embodiment.
[0032] A brain image classification device for Alzheimer's disease based on adaptive receptive field 3D spatial attention, including:
[0033] A data acquisition module, configured to acquire brain MRI images of T1 structural items;
[0034] The data preprocessing module is used to sequentially perform origin correction, gray matter segmentation, registration and modulation processing on the MRI images obtained by the data acquisition module;
[0035] The origin correction is to correct the origin of the MRI image to the position of the anterior commissure of the brain. Among them, the origin correction is a routine technical operation, so it will not be explained in detail.
[0036] The gray matter segmentation is to remove the skull region from the image processed by the origin correction, and then extract the gray matter region.
[0037] The registration is to register the g...
