Claim One:
1. A method for detecting the bright brain regions from computed tomography images, comprising: loading computed tomography image data; deriving images of a skull; deriving brain images; converting the brain images to lower bit images data; calculating a generalized asymmetry map with respect to the midsagittal plane (MSP); calculating a grayscale threshold, a threshold of a local contrast, a threshold of asymmetry, and a threshold of partial volume voxels for bright brain regions (BBRs); deriving initial bright brain regions (BBRs); recovering bright brain voxels symmetrical to the midsagittal plane (MSP); refining the initial bright brain regions (BBRs); checking if detected bright brain regions (BBRs) is different from an average grayscale, increasing or decreasing a window width being increased or decreased when the detected bright brain regions (BBRs) is different from the average grayscale, then and going back to the converting step; and after checking to ensure that the bright brain regions (BBRs) match the average grayscale, outputting the bright brain regions (BBRs).
