arlkup - tpcclib 0.8.0 © 2023 by Turku PET Centre

Calculation of perfusion look-up table from [O-15]H2O blood curve
for usage with PET in vivo autoradiographic (ARG) method.
Usage: arlkup [options] BTAC p fMax start dur lkupfile
     The look-up table integral can be corrected for physical decay as
     single frame when static PET scan was performed (y), or dynamically
     (N, the default).
     Set the size of look-up table; 5000 by default.
 -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.
Blood TAC (BTAC) must be calibrated and corrected for decay. Sample times
must be in sec unless correctly specified inside the BTAC file.
Concentrations must be in the same units as the units of PET tissue data.
Partition coefficient of water (p) must be given in units mL/mL,
and maximal perfusion (fMax) in units mL/(min*100mL).
Integration start time and duration is given in sec.
Look-up table will contain 2 columns: TTAC integral [sec*kBq/mL] and
blood flow [mL/(min*100mL)].
