Automatic extraction of brain regions from brain images

Abstract

In the previous study, the method of extracting brain regions from the MR brain image was proposed. That method uses Snake to detect the position of the scalp and remove scalp and skull automatically. In this study, we propose the method for automatic placement of initial contour of snake. At first, the MR brain image is divided into several small areas. Each area could be classified into the area with no object, and the area with brain parenchyma, and Composite area by considering the average and the standard deviation of histogram of the image. The position of the contour of snake can be initialized automatically by place it in the area with no object. As a future, we will apply the proposing method of placing the initial contour of Snake to several MR head images and estimate the effect by comparing with the conventional manual methods.
