Validation of magnetic resonance imaging (MRI) multispectral tissue classification

Abstract

NASA multispectral image processing technology has been adapted to the analysis of magnetic resonance imaging (MRI) scans. A statistical evaluation of multispectral analysis applied to tissue classification in MRI brain scans has been performed. The radiometric and geometric distortions introduced by the MRI scanner can be removed before feature extraction and classification. Signatures may be derived from one set of multispectral MR images at a single anatomic level and be applied in the same subject at later times, to other anatomic levels containing the same tissues, or to other subjects.<>
