absscal - tpcclib 0.7.7 © 2021 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]
Calibration coefficients for ABSS and well-counter should be specified
with calibration file (2), given with option -c.
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, ...
Blood data is corrected for radioactive decay (on, default), or not
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.
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.
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 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.
Display usage information on standard output and exit.
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.
Suppress displaying normal results on standard output.
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.
