Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 14:
15. A magnetic resonance imaging apparatus, comprising:
a) means for providing images of signals at a multitude of contrast-weighting levels;
b) means for selecting predefined contrast-weighting levels;
c) means for performing at each image pixel position a higher-order function fit to the multitude of measured contrast-weighting level dependent signals at said pixel position;
d) means for determining for each said signal pixel position computed signal values from said higher-order function fit at said predefined contrast weighting levels;
e) means for performing at each said pixel position a monoexponential function fit through said computed signal values related to said pixel position at said predefined contrast weighting levels and determine a monoexponential decay parameter; and
f) means to assemble said monoexponential decay parameter of all image pixel positions to a parameter map for display.
