A method of separating the white matter and the grey matter from brain image and calculating the volume of thereof

摘要

By removing the areas other than the brain, the brain image of a PD image and remove cerebrospinal fluid from the corresponding pre-processing process of removing the same area in the T2 images and, T2 image the pre-processing is complete, remove the cerebrospinal fluid of the same area in the PD images corresponding while by using that cerebrospinal fluid separation process, a PD image in which cerebrospinal fluid separation generates a histogram by increasing the contrast value in the process, a histogram is calculated for each part by volume of the white matter and gray matter calculate the integral of the distribution function the value generating the white matter and gray matter separation image for each slice of the first intensity value greater than the sum of the parts by volume of the white matter, based on the determination value calculation process, a determination value used to set the discrimination value, and white matter and gray matter each of the white matter and gray matter by using the information provided from the slice of the portion and volume information tomography volume of Methods Isolation and volume calculation of the white matter and gray matter in the brain images, characterized in that comprising the step of calculating.
