Analysis method and device for cerebrovascular image based on cerebrovascular chunk features

An analysis device for analyzing a cerebrovascular image based on cerebrovascular chunk features, the device comprising:

• an input unit receiving a cerebrovascular image of a subject;
• a storage unit storing a learning model that classifies chunks to which a vascular unit structure belongs;
• and
• a computing unit extracting a plurality of vascular unit structures based on geometric features of a 3-Dimensional (3D) model from the cerebrovascular image, inputting feature values for each of the plurality of vascular unit structures into the learning model to classify chunks to which each of the plurality of vascular unit structures belongs and generate chunk features for the cerebrovascular image, and evaluating a condition of the subject based on the chunk features, wherein the vascular unit structure is a spot, and the spot is a cell arranged at regular intervals along an artery center line extracted from the cerebrovascular image.

A method of analyzing a cerebrovascular image based on cerebrovascular chunk features, the method comprising:

• receiving, by an analysis device, a cerebrovascular image of a subject;
• extracting, by the analysis device, a plurality of vascular unit structures based on geometric features of a 3-Dimensional (3D) model from the cerebrovascular image;
• extracting, by the analysis device, feature values for each of the plurality of vascular unit structures;
• inputting, by the analysis device, the feature values of each of the plurality of vascular unit structures into a learning model trained in advance, and classifying chunks to which each of the plurality of vascular unit structures belongs;
• determining, by the analysis device, characteristic information on a plurality of chunks segmented in the cerebrovascular image based on the feature values of the vascular unit structure belonging to the chunk;
• and
• evaluating, by the analysis device, a condition of the subject based on the characteristic information on the plurality of chunks, wherein the vascular unit structure is a spot, and the spot is a cell arranged at regular intervals along an artery center line extracted from the cerebrovascular image.
