Comments on "Partial-volume Bayesian classification of material mixtures in MR volume data using voxel histograms"

H. Soltanian-Zadeh and J.P. Windham read with interest a paper by D.H. Laidlaw et al. (see ibid., vol. 17, no. 1, p. 74-86, 1998). H. Soltanian-Zadeh and J.P. Windham felt that the methods D.H. Laidlaw et al. presented are interesting and illustrate the significance of partial volume information in medical image analysis. However, D.H. Laidlaw et al. seem to be unaware of the details of the literature on optimal partial volume estimation from MRI, although they cite one of the references. As such, there are a few important points that D.H. Laidlaw et al. did not describe correctly. The purpose of this communication by H. Soltanian-Zadeh and J.P. Windham is to explain these points.
