A method and system for measuring core infarction volume based on head CT images

Abstract

The embodiment of this specification discloses a method and system for measuring core infarct volume based on cranial CT images, belonging to the field of medical imaging. The embodiment of this specification solves the problems of large subjectivity differences and poor accuracy of core infarction volume measurement results in the prior art through the measurement method of core infarction volume based on head CT images. The measurement method includes: determining the frame where the target image layer is located from the multi-frame head CT image data to be processed; extracting the target area; performing infarction judgment on each target area included in the target area, and outputting the infarction judgment result; Regional infarct judgment results, measuring the core infarct volume. The measurement method and system provided in the embodiments of this specification can quickly and accurately measure the core infarct volume, eliminate or reduce the interference of subjective factors, and serve as a computer-aided method to provide objective evidence for stroke and other medical research.

Description

technical field [0001] This specification relates to the fields of medical imaging and computer technology, and in particular to a method and system for measuring core infarct volume based on head CT images. Background technique [0002] Core infarction is one of the important indicators in the evaluation of acute ischemic stroke (AIS). Among them, core infarction refers to the brain tissue with irreversible damage, which refers to the area where the cerebral blood flow decreases by more than 30% compared with normal brain tissue, and it is displayed as low density area. The size of the infarct core is closely related to the clinical prognosis of patients. The smaller the infarct core, the greater the likelihood that the patient will have a good prognosis. At the same time, evaluation of the infarct core can also predict the risk of complications of endovascular therapy. Therefore, accurate evaluation of the infarct core is helpful for screening stroke patients who are su...

AI Technical Summary

Problems solved by technology

Among them, the key to manually measuring the core infarct volume is to manually outline the infarct focus, which is very cumbersome and has great limitations in accuracy, repeatability, and objectivity.

Computer-aided measurement of core infarct volume mostly uses the method of image segmentation for measurement, but this method will lose some information in the process of processing, which will affect the measurement results
