Abstract
A large vessel occlusion (LVO) test device using eyeball deviation includes an image input unit configured to input non-contrast computed tomography (CT); a pre-processing unit; an image processing unit; and a determination unit. The objects include both eyes and the upper part of the brain corresponding to the entire cerebral cortex from the midbrain. The image processing unit configured to non-rigid register at least one atlas for the non-cis contrast CT images pre-processed from the pre-processing unit, normalize each cell of the non-contrast CT image to which the atlas is registered to have a value of 0 or 1, and extract a region of interest in a restored non-contrast CT image by combining each cell of the non-contrast CT image to which the atlas is registered through inverse transformation.
