摘要：
The present invention relates to an AI-based auxiliary diagnostic system for the diagnosis of cerebrovascular disease. The AI-based auxiliary diagnostic system according to the present invention includes a learning database in which a plurality of MRA images labeled with cerebrovascular diseases are stored, a coordinate system registration module for registering a spatial coordinate system in each of the MRA images stored in the learning database, and the coordinate system. And an AI module for learning the MRA images in which the spatial coordinate systems are respectively registered by a registration module through a pre-registered deep learning based learning model； The coordinate system registration module includes (a) extracting a vascular region from the MRA image, (b) extracting three pre-set anatomical first points from the vascular region, and (c) three first Determining a normal vector for a first plane formed by the point as a first coordinate vector, and (d) extracting two predetermined anatomical second points located on both sides with the first plane interposed therebetween. And, (e) extracting a location where the first plane meets a straight line connecting the two second points as a coordinate origin, and (f) extracting a predetermined anatomical third point, (g ) Extracting a second plane formed by the two second points and the third point, and extracting an intersection line intersecting the first plane and the second plane, and (h) based on the intersection line Determining a second coordinate vector by (i) Determining a first coordinate axis and a second coordinate axis by moving the first coordinate vector and the second coordinate vector to the coordinate origin, respectively, and (j) a third orthogonal to the first coordinate axis and the second coordinate axis, respectively. And determining a coordinate axis to register the spatial coordinate system.본 발명은 뇌혈관 질환의 진단을 위한 AI 기반의 보조 진단 시스템에 관한 것이다. 본 발명에 따른 AI 기반의 보조 진단 시스템은 뇌혈관 질환이 레이블된 복수의 M
