Patent ID: 8718345

Claim:
A method for obtaining brain characteristic parameters, comprising: step S 1 , selecting a magnetic resonance perfusion weighted imaging of a patient obtained in accordance with magnetic resonance, wherein the magnetic resonance perfusion weighted imaging comprises a diffusion-weighted image, a T2-weighted image, and an apparent diffusion coefficient (ADC) map; step S 2 , distinguishing a brain tissue from a non-brain tissue in accordance with the T2-weighted image, and obtaining a brain tissue image without the non-brain tissue; step S 3 , processing voxels of the ADC map corresponding to the brain tissue image in accordance with low ADC signal constraint binarizing to obtain a binary image according to calculated ADC thresholds of a transition area; step S 4 , estimating a core area and the transition area according to the binary image and calculated ADC thresholds of the core area; step S 5 , processing the estimated core area according to high signal constraint processing in accordance with high thresholds of the diffusion-weighted image of the estimated core area, and obtaining the core area and the transition area; and step S 6 , calculating characteristic parameters of the core area and the transition area.
