Early warning system and method for cerebral apoplexy

Abstract

The invention belongs to the technical field of medical early warning, and discloses an early warning system and method for cerebral apoplexy. The early warning system for cerebral apoplexy comprisesan image collection module, a physiological index collection module, a main control module, an image processing module, a risk evaluation module, a warning module, a data storage module and a displaymodule. According to the system and method, through the image processing module, automatic identification and segmentation of a cerebral ischemia zone in a super-acute stage can be achieved, and the segmentation precision of the ischemia zone is improved; data preprocessing, feature selection and feature optimization are conducted through the risk evaluation module, and obtained data features aremore effective; an XGBoost method is adopted for automatically generating the risk probability that a target group of people suffer from cerebral apoplexy, community health screening can be more efficiently and conveniently conducted, and a doctor can be helped to more simply and quickly evaluate the risk that the target group of people suffer from cerebral apoplexy; health screening can be strongly pushed, so that potential users with cerebral apoplexy are more quickly found, and earlier warning is given, so that earlier and more effective treatment is conducted.

Description

technical field [0001] The invention belongs to the technical field of medical early warning, and in particular relates to a stroke early warning system and method. Background technique [0002] "Stroke", also known as "stroke" and "cerebrovascular accident", is an acute cerebrovascular disease, a group of diseases that cause brain tissue damage due to sudden rupture of blood vessels in the brain or blockage of blood vessels that prevent blood from flowing into the brain. Includes ischemic and hemorrhagic stroke. The incidence of ischemic stroke is higher than that of hemorrhagic stroke, accounting for 60% to 70% of the total stroke. Occlusion and stenosis of the internal carotid artery and vertebral artery can cause ischemic stroke, most of which are over 40 years old, more men than women, and severe cases can cause death. Mortality from hemorrhagic stroke is high. According to the survey, stroke has become the number one cause of death in my country combined in urban an...

Problems solved by technology

[0004] (1) The existing stroke image processing has low accuracy, large errors, and inaccurate monitoring. The risk of stroke cannot be assessed in time, resulting in inability to treat it in time

[0005] (2) The currently used medical imaging equipment has certain acquisition errors when collecting images of the user's cerebral blood vessels, and the quality of the final reconstructed image is low, which has a negative impact on the diagnosis of the user's condition

[0006] (3) At present, the influence of the filter on the collection of EEG data is serious, and it is difficult to avoid high-frequency noise in the signal. The gray level error of the existing display screen is relatively large, and the display brightness is uneven, which is not conducive to data collection. Observed
