fitmtrap - tpcclib 0.8.0 © 2023 by Turku PET Centre

Fitting of a compartmental model to regional myocardial PET data, where
radiotracer is assumed to be trapped into cells at first pass,
as chemical microspheres.
The multilinear model is
  Cpet(t) = Vb*Cb(t) + ((1-Vb)*K1+Vb*k2)*Integral[Cb(t)]
            - k2*Integral[Cpet(t)]
BTAC from LV cavity is used as input function.
Usage: fitmtrap [Options] tacfile BTAC [parfile]
 -k2=<value> | -k2=<MTAC> | -k2=median
     By default, full three-parameter model is fitted to all regional TACs
     in tacfile are fitted independently. With these options, k2 can be
     constrained to given value, or to value from a given large muscle
     region, or to the median of k2 estimates of all regions.
 -w1 | -wf
     By default, weights in data file are used, if available.
     With these options all weights can be set to 1.0 (no weighting)
     or based on frame durations.
     Fitted and measured TACs are plotted in specified SVG file.
     Fitted TACs are written in specified TAC file.
     Input (1-HCT)*PTAC is written in specified file.
     Input curves are plotted in specified SVG file.
