An Attempt for Coloring Multichannel MR Imaging Data

ÐThis is an elementary research for assigning color values to voxels of multichannel Magnetic Resonance Imaging (MRI) volume data. The MRI volume data sets obtained under different scanning conditions are transformed to the components by independent component analysis (ICA), which enhances physical characteristics of the tissue. The transfer functions for generating color values from independent components are obtained using the radial basis function network, a kind of neural net, by training the network with sample data chosen from visible human female data set (VHF). The resultant color volume data sets correspond well with the full-color cross-sections of the visible human data sets. Index TermsÐColor MRI, independent component analysis, transfer function.
