A method and system for measuring morphological parameters of intracranial aneurysm images

Abstract

The embodiment of this specification provides a method and system for measuring morphological parameters of an intracranial aneurysm image. The embodiment of this specification solves the problem that the measurement of the morphological parameters of the intracranial aneurysm image cannot be fully automated and the measurement consistency is difficult to guarantee by measuring the morphological parameters of the intracranial aneurysm image. The measurement method includes: segmenting the intracranial parent vessel image from the three-dimensional DICOM data of DSA; segmenting the intracranial aneurysm image based on the center line and radius of the intracranial tumor parent vessel; analyzing the morphology of the intracranial aneurysm image The scientific parameters are measured. The method and system for measuring the morphological parameters of intracranial aneurysm images provided in the embodiments of this specification can realize the automation of intracranial aneurysm image measurement, quickly measure the morphological parameters of intracranial aneurysm images, and ensure the accuracy of aneurysm images. Consistency of measurements of morphological parameters.

Description

Technical field [0001] This specification relates to the field of medical imaging, and more particularly to the measurement method and system of morphological parameters of intracranial aneurysm images. Background technique [0002] The intracranial aneurysm is a tumor-like protrusion from a local abnormal expansion of the intracranial artery inner cavity, which is a common vascular disease. According to reports, the intracranial unfaracted aneurysm is as high as 7% in our adults. After breaking, it can cause severe disability or death. In 2014, the National Bureau of Statistics showed that acute cerebral vascular diseases were the second largest death cause of China 's population. Aneurysm subjunctiva hypertezers is the most common acute cerebrovascular disease after ischemic stroke and high blood pressure, and the dead loss rate is as high as 64%, about 15% of the patients who die, and different economic development. The treatment level is very different, and it has become one ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the measurement of intracranial aneurysm images basically relies on experienced personnel, using computer manual measurement, the measurement speed is slow, the measurement results are random, and the accuracy is not ideal, and this method can only measure simple parameters, such as line segments Distance; for complex parameters such as volume or angle, manual measurement is very inconvenient and the accuracy is difficult to guarantee

The improvement of aneurysm measurement is mainly the improvement of simulation modeling or traditional manual measurement methods, which cannot realize the automatic measurement of aneurysm morphological parameters, and its consistency is difficult to guarantee
