Transverse Weighting Compares Visible Fractions - Biophysical Instrumentation VII: NMR Relaxation and MRI Contrast Step by Step

The transverse contrast uses toy visible fractions, not fitted decay constants.

The transverse contrast uses toy visible fractions, not fitted decay constants. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

Toy transverse fractions are visible fractions

The brighter row keeps 9 of 12, or 3/4.

9/12=\frac{3}{4}

The dim row keeps one half

The contrast row keeps 6 of 12, or 1/2. No real transverse decay constant is being fitted.

6/12=\frac{1}{2}
