Method for auxiliary diagnosis of acute ischemic stroke based on CT flat scanning images

Abstract

The invention discloses an image processing method based on a CT (computed tomography) flat scanning image. The method assists in evaluating the CT early ischemic change degree of the head of an AIS (acute ischemic stroke) patient. According to the invention, the risk assessment of the automatic zoning and quantitative treatment of the acute ischemic stroke from the CT flat scanning images is realized, and an effective assessment method is provided for the early screening, early diagnosis and early treatment of patients with the acute ischemic stroke (AIS).

Description

technical field [0001] The invention relates to a method for auxiliary diagnosis of acute ischemic stroke based on plain CT images, belonging to the field of computer image processing. Background technique [0002] With the development of the country's economy and the improvement of living standards, the incidence of brain diseases is also increasing. Stroke, as the leading cause of death in my country, has 270 million high-risk groups in China, 12.42 million patients, 5.5 million new cases each year, more than 2 million deaths each year, 3.5 million hospital admissions each year, and more than 40% recurrence in three years. Direct medicine The cost is 40 billion / year, and the timely treatment rate is only 2%, which has become an important reason for my country's poverty due to illness and return to poverty due to illness. Although imaging technology in the field of medical devices is also improving, image post-processing still relies on cumbersome manual operations and mark...

Problems solved by technology

[0004] At present, clinical practice mainly relies on the naked eye observation of medical technicians, but due to the insufficient quantification of the scoring method, different doctors may give different scoring results, so that the final ASPECTS score will have errors
