This paper proposes a segmentation method for a quantitative image diagnosis of the frontal lobe atrophy. From the data obtained on the grade of membership, the fractal dimensions of the cerebral tissue (cerebral spinal fluid (CSF), gray matter, and white matter) and the contours are estimated. The mutual relationship between the degree of atrophy and the fractal dimension has been analyzed based on the estimated fractal dimensions. Using a sample of forty-two male and female cases, ranging in age from fifties to seventies, it has been concluded that the frontal lobe atrophy can be quantified by regarding it as an expansion of CSF region on the Magnetic Resonance Imaging (MRI) of the brain. Further, when the process of frontal lobe atrophy is separated into early and advanced stages, the volumetric change of CSF and white matter in frontal lobe displays meaningful differences between the two stages, demonstrating that the fractal dimension of CSF rises with the progress of atrophy. Moreover, an interpolation method for 3-D shape reconstruction of the region of diagnostic interest is proposed and 3-D shape visualization, with respect to the degree and form of atrophy, is performed on the basis of the estimated fractal dimension of the segmented cerebral tissue.
