Problems solved by technology

However, due to the variation of cerebral arteries in the population, that is, different patients will have different structures of cerebral arteries, and the blood supply area will be different, so the final ASPECTS score will have errors

Abstract

The invention discloses a blood supply area quantification method and system based on enhanced angiography. Firstly, CTA (computed tomography) or MRA (magnetic resonance imaging) of the brain are utilized to segment cerebral artery blood vessels to obtain the central line and lumen diameter of each segment of blood vessels, then Venogram operation is carried out based on the central point of eachsegment of blood vessels, and the lumen diameter of each central point is used for weighting, so that the blood supply area of the cerebral artery is divided to clearly determine each segment of the cerebral artery, for example, blood supply areas of the superior trunk of the middle cerebral artery, the inferior trunk of the middle cerebral artery and the anterior cerebral artery, and finally a CTmean value of each of CT images in the blood supply areas is calculated for evaluation of medical workers on signal values in each blood supply area. According to the blood supply area quantificationmethod and system, division is carried out based on individual conditions such as the thickness and shape of intracranial blood vessels, and compared with ASPECTS scoring carried out only based on ablood supply area of a fixed anatomical template, the method and the system are more direct and accurate.

Description

technical field [0001] The invention belongs to the technical field of medical image processing, and relates to a blood supply area quantification method, in particular to a blood supply area quantification method and system based on angiography-enhanced angiography. Background technique [0002] ASPECTS (Alberta Stroke Program Early CT Score) score is an important basis for the diagnosis and treatment of stroke. This scoring method is aimed at patients with acute stroke, and divides the important levels of blood supply of the middle cerebral artery into 10 regions according to the head CT image data, such as figure 1 As shown, the above-mentioned 10 regions have the same weight, each accounting for 1 point, and the total score is 10 points. The number of regions with early ischemic changes is subtracted from the total score, and the obtained value is used as the scoring result, which is used for disease judgment and diagnosis. The basis for treatment. [0003] At present,...
