In this paper we present a fast automated three-dimensional brain segmentat
ion and brain volumetry method providing minimal requirements of the number
of spectral MR image channels and the performance of the computer equipmen
t employed. The presented method is based on standard non-iterative two-dim
ensional grey level segmentation techniques in combination with pixel vecto
r-oriented classificators and morphological operators and requires a bispec
tral high resolution MR data base. In its current design, the method provid
es for the largely partial volume-corrected determination of the cerebrospi
nal fluid (CSF) and the white and grey brain matter volumes of the human br
ain. For the verification of our approach, the results of applications to c
linical data were compared to those of studies found in the literature. (C)
