Hi,
ImageJ has got a curve fitter.
I am looking for a "time-domain" or "z axis" image fitter.
I would like to have for each pixel of a stack, a fit (actually
gamma-variate)  along the z axis. It could return a stack with the same z
values, but where the pixels values would be predicted from the fit, or
alternatively another stack with the coefficients of the fit.
I would use that to analyse MRI data following first-pass in the brain of a
contrast agent to derive cerebral blood volume and mean transit time.
Does anyone know a plugin, macro which already does that or could be adapted ?
Thanks in advance,
Cheers,
Simon
