Patent ID: 8165362

Claim:
A method of detecting a neurodegenerative disease, comprising: a standardization step of creating a first image by applying anatomical standardization to a brain nuclear medical image; a conversion step of creating a second image by converting the pixel value of each pixel of an image based on the first image into a z score or a t value; an addition step of calculating the sum of the pixel values of individual pixels in a predetermined region of interest in the second image; and a detection step of obtaining the results of the detection of the neurodegenerative disease through an operation of comparison of the sum with a predetermined threshold, wherein the region of interest is preliminarily set as a region formed by extracting pixels having a z score of three or more obtained by comparison of a disease group having a certain number of individuals with a normal group having a certain number of individuals; forming clusters from pixels adjacent to one another among the extracted pixels; and selecting a cluster having the largest size among the formed clusters to extract the outline of the selected cluster.
