Problems solved by technology

[0005]Related technologies generally realize the recognition of medical images of patients with Alzheimer's disease by analyzing the collected medical images. However, in the process of medical image analysis, due to the The etiology of Haimer's disease is unknown so far, and the ROI ((region of interest) performance of selected medical images is not good, resulting in low accuracy of final image classification

Abstract

The embodiment of the invention discloses a medical image classification device and system. The device comprises a classifier pre-construction module and an image classification module. The classifierpre-construction module is used for extracting a plurality of ROI images of each medical sample image in the training sample set, and then each class of ROI images is trained by utilizing a three-dimensional convolutional neural network to obtain corresponding base classifiers; and an optimal base classifier is selected from the plurality of base classifiers by using a genetic algorithm based ona preset fitness value, and finally an image classifier is generated based on each optimal classifier. The image classification module is used for inputting the to-be-identified medical image into a pre-constructed image classifier to obtain a classification result of the to-be-identified medical image. According to the device and sytem, the accuracy of medical image classification is improved, the medical image of the early-stage Alzheimer's disease can be accurately recognized, and assistance is provided for prevention and diagnosis of patients with the early-stage Alzheimer's disease.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical image processing, and in particular, to a medical image classification device and system. Background technique [0002] Alzheimer's disease is a progressive neurodegenerative disease with insidious onset, which can be detected by structural imaging or functional neuroimaging in medicine. [0003] Structural imaging such as head CT (Computer Tomography, computed tomography) and MRI (Magnetic Resonance Imaging, magnetic resonance imaging) examinations can show obvious cortical atrophy, especially the hippocampus and medial temporal lobe, supporting the clinical diagnosis of Alzheimer's. Functional neuroimaging such as positron emission tomography and single-photon emission computed tomography can improve the diagnostic confidence of dementia. [0004] The clinical manifestations of Alzheimer’s disease are different in different stages, such as the decrease of frontal lobe meta...
