dftcbv - tpcclib 0.7.4 © 2019 by Turku PET Centre

Subtracts the contribution of vascular radioactivity from regional
PET TTACs. Vascular volume fraction Vb can be given as a value that is
common to all regions, or as regional Vb values in a TAC file, calculated
from a [O-15]CO study.
Usage: dftcbv ttacfile btacfile Vb outputfile
     Negative TAC values are set to 0.
 -pv | -tv
     Equation Ct=Cpet-Vb*Cb is applied by default or with option -pv;
     with option -tv equation Ct=(Cpet-Vb*Cb)/(1-Vb) is applied.
     Simulate the contribution of vascular radioactivity instead of
     correcting for it, calculating Cpet from Ct using equations above.
 -h, --help
     Display usage information on standard output and exit.
 -v, --version
     Display version and compile information on standard output and exit.
 -d[n], --debug[=n], --verbose[=n]
     Set the level (n) of debugging messages and listings.
 -q, --quiet
     Suppress displaying normal results on standard output.
 -s, --silent
     Suppress displaying anything except errors.
Example 1:
     dftcbv uo372.tac uo372ab.bld 0.045 uo372cbv.tac
Example 2:
     dftcbv uo372.dft uo372ab.kbq uo372vb.dft uo372cbv.dft
Vb values that are >=1.0 are assumed to be percentages.
Blood TAC can be given in a separate BTAC file, or as a region id inside
TTAC file.
