Abstract

The invention provides an early acute cerebral infarction detection method and device. The early acute cerebral infarction detection method comprises the following steps of: acquiring a plurality of diagnosed early acute cerebral infarction brain CT images; constructing an early acute cerebral infarction detection model based on a 2.5 D segmentation network; training the early acute cerebral infarction detection model through the early acute cerebral infarction brain CT images; and inputting a to-be-detected brain CT image, performing early acute cerebral infarction probability prediction on each voxel point of the to-be-detected brain CT image through the trained early acute cerebral infarction detection model, and realizing early acute cerebral infarction detection according to a prediction result. According to the invention, early acute cerebral infarction can be automatically detected, and the method has high efficiency and accuracy.

Description

technical field [0001] The invention relates to the technical field of image processing and analysis, in particular to a method for detecting early acute cerebral infarction and a device for detecting early acute cerebral infarction. Background technique [0002] Early acute cerebral infarction refers to the necrosis of brain tissue caused by the sudden interruption of cerebral blood supply. Usually, it is mainly due to atherosclerosis and thrombosis in the arteries supplying blood to the brain, which narrows or even occludes the lumen, resulting in focal acute cerebral insufficiency; there are also abnormal objects (solid, liquid, gas) circulating along the blood. Entering the cerebral arteries or the carotid arteries supplying cerebral blood circulation, resulting in blockage of blood flow or a sudden decrease in blood flow, resulting in softening and necrosis of the brain tissue in the corresponding dominating area. Brain magnetic resonance scan can diagnose early acute ...
