ABSS calibration
Corrections for Swisstrace ABSS are done in PMOD PSAMPLE software. This page applies to the other blood sampling systems.
Calibration of ABSS data
Calibration of automatic blood sampling systems data includes
- ABSS specific detector-to-gamma counter coefficient
- gamma counter-to-pet coefficient, common to all ABSSs
- isotope-specific branching ratio correction
All calibration steps can be done using program blo2kbq (absscal). In short, counts/sec values from ABSS are multiplied by detector calibration factor and gamma counter-to-pet coefficient, and divided by the branching ratio.
Calibration file
In TPC, physicists are responsible of the calibration measurements and the updating of
the calibration file, currently in S:\Lab\plasma\bsampler_calibration\pump_cal.dat.
The calibration file is in ASCII text format, and it contains the calibration dates, and the above mentioned calibration coefficients.
The contents of the ABSS calibration file on Spring 2014 was:
