imgpeak - tpcclib 0.7.8 © 2022 by Turku PET Centre

Find peak value and time in dynamic PET image.
Static image containing the peak value of each pixel TAC is written.
 
Usage: imgpeak [Options] imgfile [peakfile]
 
Options:
 -frame=<filename>
     Save a template image containing the frame numbers (1..frame_nr)
     where the maximum pixel values were found.
 -mpt=<filename>
     Save TAC file, containing the frame times (sec) on x-axis, and on
     y-axis the means (and mean-SD and mean+SD) of the peak values of
     each pixel that had its peak at this frame time.
 -time=<filename>
     Save the peak time (sec) of each pixel (middle time of peak frame).
 -wt=<filename>
     Save the peak time (sec) of each pixel, calculated as weighted
     average of 3 or 5 subsequent frames.
 -ct=<filename>
     Save the value-weighted mean time (sec) of all frames.
     Mean residence time (MRT) in PK for PTACs uses the same equation.
 -thr=<threshold%>
     Use only pixels with peak value above (threshold/100 x max peak);
     default is 5%.
 -norm[alize]
     Maximum pixel values are divided by the frame average.
 -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.
