mkcalhdr - tpcclib 0.8.0 © 2023 by Turku PET Centre

Calculates HRRT calibration factor, assuming that there is a cylindrical
phantom with 20 cm diameter in the FOV.
Resulting calibration header file is written in file
STUDY_RECMETHOD_iMNsXY_sS.cal.hdr, where STUDY is the part of the calibration
study name preceding delimiter "_", "-", "."  or space, RECMETHOD is
the utilised reconstruction method, iMN is the number of iterations preceded
by char i, sXY is the number of subsets preceded by char s and sS is the span
preceded by char s. If calibration is calculated for 128x128 matrix size,
suffix m128 is appended in header file name.
 
Efficient (sensitivity) factor for each plane is calculated as mean over
planes 19-188 divided by plane average. Efficient factor is set to zero for
planes 1-6 and 201-207 (HRRT has 207 image planes).
 
Usage: mkcalhdr [Options] -a=<Activity> Interfile(s)
 
Options:
 -a=<Activity> or -a <Activity>
     Activity concentration at scan start time in Bq/mL; required option.
 -l=<First eff plane> or -l <First eff plane>
     First plane for which the efficient factor is set; default is 7.
 -L=<Last eff plane> or -L <Last eff plane>
     Last plane for which the efficient factor is set; default is 200.
 -m=<First mean plane> or -m <First mean plane>
     First plane used for mean calculation; default is 19.
 -M=<Last mean plane> or M <Last mean plane>
     Last plane used for mean calculation; default is 188.
 -sd=<Y|n>
     Calculate standard deviation inside VOI (y, default), or not (n).
 -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.
