Abstract :
A fast and robust algorithm to segment the head from T1-weighted magnetic resonance (MR) volumes is presented based on robust determination of threshold from combination of the original volume (through employing the fuzzy c-means clustering which is insensitive to intensity inhomogeneity) and the average axial image (which suppresses the intensity noise), efficient connected component analysis through iterative recursion and fast implementation of morphological operations via decomposition of structuring elements. The algorithm has been validated against 101 data sets with various artifacts
