T2 distribution or spectrum?
Submitted by thor on Tue, 02/12/2008 - 20:19.
It is common in the quantitative T2 literature to see the term "T2 spectrum" instead of "T2 distribution". Using the word "spectrum" has certain implications that are simply wrong for a T2 distribution. For example, what is the Fourier tranform of a T2 spectrum?
Unfortunately, Ken Whittall's 1989 paper uses T2 spectrum and likely contributes to the different phraseology in the literature. However, work from the UBC group following the 1989 article use T2 distribution.

you're right ... to some extent
spectrum indeed means "frequency"
However "T2 distribution" seems equally ackward (don't you think?)
It is overall not continuous

continuous?
I disagree. Both spectrum and distribution are not continuous in MR, since we discretise everything when we measure it. So, both distribution and spectrum suffer from not technically being continuous. I think that the, potentially confusing, frequency connotations from spectrum would be eliminated using distribution.
