Abstract
Quantified differences, such as chi2 error parameters, between a mono-exponential, logarithmic best fit of a series of line scan diffusion-weighted magnetic resonance signals taken over a range of b-factors between about 100 and about 5000 sec/mm2 are obtained. The quantified differences so generated are displayed as an image wherein the brightness of each pixel depends upon the size of its associated quantified difference. The resulting image is characterized by high signal to noise ratio and distinctness between varying tissue types.
