A method and a system for measuring a core infarction volume based on a skull CT image

Abstract

The embodiment of the invention discloses a method and system for measuring the core infarction volume based on a skull CT image, and belongs to the field of medical images. According to the method for measuring the core infarction volume based on the skull CT image, the problems that in the prior art, the subjective difference is large, and the core infarction volume measurement result is poor inaccuracy are solved. The method for measuring the core infarction volume comprises the following steps: inputting a plurality of frames of skull CT image data to be processed into an infarction recognition model obtained by pre-training; Recognizing the head CT image data through an infarction recognition model to obtain infarction probability of the head CT image data; And measuring the core infarction volume based on the infarction probability of the skull CT image data. According to the measurement method and system provided by the embodiment of the invention, the core infarction volume can be rapidly and accurately measured, interference of subjective factors is eliminated or reduced, and an objective basis is provided for medical research such as cerebral apoplexy and the like as a computer-aided method.

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, assessing the infarct core can also predict the risk of complications of endovascular treatment. Therefore, accurate assessment of the infarct core is helpful for screening stroke patients who are suit...

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
