The invention provides an
evaluation system and evaluation method for an early noncontrast
computed tomography (CT) image of
stroke, and a readable storage medium. The
evaluation system includes a preprocessing module, a brain
blood supply area segmentation module, a segmentation scoring module and a comprehensive scoring module; a brain
parenchyma segmentation unit can realize the
processing of removing a
skull and retaining a brain
parenchyma of the noncontrast CT image; the brain
blood supply area segmentation module is used to register a brain
blood supply area template image to the noncontrast CT image, and map a plurality of segmented blood supply areas marked in the brain blood supply area template image to the noncontrast CT image registered with the areas to obtain a plurality ofsegmented blood supply areas in the noncontrast CT image; and the comprehensive scoring module is used to
score the image performance of each segmented blood supply area in the noncontrast CT image toobtain an overall
score of the noncontrast CT image. The
evaluation system can assist doctors for diagnose in the early diagnosis and treatment of the
stroke, reduce the subjective difference of thedoctors, and help improve the diagnosis efficiency and accuracy; and the evaluation method and the readable storage medium have the same advantages.
