absscal - tpcclib 0.8.1 © 2025 by Turku PET Centre

Extraction and calibration of blood TACs measured using
automatic blood sampling systems (ABSS, "blood pump") (1).
Application name was previously blo2kbq, version 3.8.1.
 
Usage: absscal [Options] ABSS_file [BTAC_file]
 
Options:
 -c=<filename>
     Calibration coefficients for ABSS and well-counter should be specified
     with calibration file (2), given with option -c.
 -i=<isotope>
     If ABSS data file does not contain the isotope code or halflife, then
     it can be given with this option, using codes
     C-11, F-18, Ga-68, Ge-68, O-15, ...
 -decay=<on|off>
     Blood data is corrected for radioactive decay (on, default), or not
     corrected (off).
 -start=<t>
     If ABSS measurement was not started at the time of injection,
     the delay t (sec) must be entered with option -start=<t>. If data
     collection was started before injection, enter a negative value for t;
     activities before that time are removed from the output data.
 -density[=<blood density>]
     With this option blood radioactivity concentrations (kBq/mL) are
     divided by the given blood density (by default 1.06)
     to get concentrations in units kBq/g.
 -min
     Sample times are written in minutes (in seconds by default).
 -mean, -left, -right, -both
     The counts or radioactivity concentrations are by default calculated
     as the mean of the channels (-mean). With options -left and -right 
     only the left (ch2) or right (ch1) channel is used.
     With option -both the results from both channels are saved.
     Only applicable to Scanditronics and GEMS data.
 -abss=<device>
     ABSS produces device-specific file formats, and detectors have
     calibration factors. This option is needed if ABSS can not be correctly
     determined from the filename (*.lis, *.bld, *.alg, or *.txt).
     Accepted devices are Scanditronics, GEMS, Allogg1, and Allogg2, or
     numbers 1-4, accordingly.
 -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.
 
Filename for corrected blood TAC data can be entered as the last command-line
argument. If not given, then file is written to the directory where ABSS file
is; calibrated file is named *.kbq and non-calibrated *.dat by default.
 
Example:
  absscal -i=O-15 -c=S:/Lab/plasma/bsampler_calibration/pump_cal.dat sr452_blo.bld
