Abstract
The present invention scanes a plurality of MRI images while varying conditions for a sample usable in color-determination and MRI imaging, subjects the image data to a first independent component analysis to decompose the data into L independent component images, selects N points on the sample to create a training sample that is a set of L (typically three) independent-component image luminances and color components. This generates as many transfer functions as the color components which output one color component for an arbitrary combination of the L independent-component image luminances. For a colored MRI generating object a plurality of MRI images are scanned while varying conditions, and a second independent component analysis on the MRI images accomplishes generating L independent component images. A calibration process scaling luminance is executed and the transfer functions are applied to the calibrated independent component images to obtain a multichannel MRI color image.
