Cerebral hemorrhage CT image classification method based on image sequence analysis

Abstract

The invention discloses a cerebral hemorrhage CT image classification method based on image sequence analysis. The method belongs to the technical field of medical image analysis, and the operation process comprises the steps of brain CT image data acquisition, data imaging processing, model construction and classification method implementation. The method comprises the following specific operation steps: acquiring a brain CT scanning result to obtain brain CT image original data; performing imaging processing on the original data of the brain CT image to form a three-channel image sequence as the input of a subsequent model; constructing a model comprising a channel attention module and a space attention module to extract features of the three-channel image sequence; according to the method, the model is trained to optimize parameters, cerebral hemorrhage positive is recognized, cerebral hemorrhage subtypes are distinguished, cerebral hemorrhage CT images are classified, CT scanning image information can be fully utilized by the model, attention to key information in an image sequence is improved, the judgment process of the whole method conforms to the diagnosis process of doctors in a real scene, and the diagnosis efficiency is improved. And the cerebral hemorrhage classification effect can be improved.

Description

technical field [0001] The invention belongs to the technical field of medical image analysis, and relates to a method for classifying CT images of cerebral hemorrhage based on image sequence analysis. Background technique [0002] With the continuous development of computer-related technologies, artificial intelligence methods are increasingly used in various fields, and medical image analysis related work based on machine learning and deep learning methods can improve the diagnostic efficiency of clinically related diseases and reduce the workload of doctors. ;In the clinical diagnosis of cerebral hemorrhage, it is often based on the patient's brain computerized tomography (CT) image results. This medical image performs a predetermined interval of tomographic scans on the brain and obtains multiple image layers. The scan time is fast and the image With sufficient clarity, non-contrast-enhanced plain scans are generally preferred in clinical CT examinations; cerebral hemorr...
