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]
 
Options:
 -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.
 -svg=<Filename>
     Fitted and measured TACs are plotted in specified SVG file.
 -fit=<Filename>
     Fitted TACs are written in specified TAC file.
 -input=<Filename>
     Input (1-HCT)*PTAC is written in specified file.
 -isvg=<Filename>
     Input curves are plotted in specified SVG file.
