A Fully Automatic Scheme for Skull Stripping from MRI of Head Scans Using Morphological Neck Breaking Operations

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 222)

Abstract

In this paper we propose a fully automatic method for extracting brain portion from T1 weighted MRI of human head scan. The proposed scheme comprise of simple image manipulation methods, intensity thresholding, image binarization, largest connected component analysis, 2D Euclidean distance and morphological operations. Application of our scheme on 20 volumes of MRI data sets shows that the proposed scheme performs better than the existing popular method Brain Extraction Tool (BET) and Brain Surface Extractor (BSE). The proposed scheme gives an average value of 0.944 and 0.970 for the similarity indices Jaccard and Dice.
