Abstract: Disclosed are a cranial CT-based grading method and a corresponding system, which relate to the field of medical imaging. The cranial CT-based grading method as disclosed solves the problems of relatively great subjective disparities and poor operability in eye-balling ASPECTS assessment. The grading method includes: determining frames where target image slices are located from to-be-processed multi-frame cranial CT data; extracting target areas; 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.

Abstract: A light diffusion plate is configured to be assembled with a blue light source module having blue Mini LEDs to form a white light backlight module. The light diffusion plate is added with organic dyes with light-emission wavelength of 490-650 nm in order to convert the blue light into white light. The light diffusion plate is made by a foaming extrusion process and contains a plurality of micro-bubbles with a size of 60-400 ?m and a weight-reduction ratio of 15-25% for improving the uniformity of white light and resolving the MURA problem. The size of micro-bubbles is controlled by reducing the temperature of at the exit end of the T-die head, such that the wavelength of the white light emitted from the light diffusion plate can be narrower to achieve the effect of wider color gamut display.
