Aneurysm analysis method and device

Abstract

The embodiment of the invention discloses an aneurysm analysis method and a device, and the method comprises the steps: carrying out the registration of first image data and second image data, and obtaining a registration image, the obtaining time of the first image data is earlier than the obtaining time of the second image data; performing three-dimensional surface reconstruction on the registration image and the first image data to obtain a blood vessel reconstruction image; and performing aneurysm analysis on the vascular reconstruction image to obtain an aneurysm analysis result. By adopting the method provided by the embodiment of the invention, the influence of human factors can be eliminated or reduced, the growth change of the aneurysm can be visually understood, rapid diagnosis is realized, and popularization and application are facilitated, so that an observer can analyze the aneurysm more visually and clearly.

Description

technical field [0001] This description relates to the field of imaging, in particular to an analysis method and device for aneurysms. Background technique [0002] Follow-up, as a method to understand the changes in patients' condition and guide patients' recovery, is of great significance for improving the service level of the hospital before and after the treatment, tracking and observing the patients, accumulating experience, and improving the professional level. [0003] MRA (Magnetic Resonance Angiography, Magnetic Resonance Angiography) is a main method of follow-up of intracranial aneurysms. During the follow-up process, the changes of aneurysms can only be observed from current aneurysm images and historical aneurysm images through subjective vision. , but the growth and changes of aneurysms are difficult to observe through subjective vision.

[0003] MRA (Magnetic Resonance Angiography, Magnetic Resonance Angiography) is a main method of follow-up of intracranial aneurysms. During the follow-up process, the changes of aneurysms can only be observed from current aneurysm images and historical aneurysm images through subjective vision. , but the growth and changes of aneurysms are difficult to observe through subjective vision

This subjective visual observation method often relies on the experience of the observer, and there are subjective judgment factors. The change of the aneurysm requires the observer's thinking, and the observation time is relatively long. Therefore, this subjective visual observation method allows the observer to judge the aneurysm. Growth changes cause trouble
