Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A cranial computed tomography (CT)-based grading method, comprising:
determining frames where target image slices are located from to-be-processed multi-frame cranial CT data, wherein the target image slices refer to the slices, where the cranial CT data for being graded are located, in the cranial CT;
extracting target areas based on the frames where the target image slices are located, wherein the target areas refer to areas for being graded in the cranial CT data;
performing infarct judgment on each target area included in the target areas to output an infarct judgment outcome regarding the target area; and
outputting a grading outcome based on infarct judgment outcomes regarding all target areas,
wherein the grading outcome eliminates diagnosis disparities and/or provides objective references for medical studies on stroke,
wherein the extracting target areas based on the frames where the target image slices are located specifically comprises:
classifying each pixel point in the cranial CT data using digital labels based on the frames where the target image slices are located and outputting a two-dimensional matrix with digital labels corresponding to respective pixel points in the frames where the target image slices are located, wherein the digital labels are in one-to-one correspondence with the target areas, and the two-dimensional matrix is in correspondence with the frames where the target image slices are located.
