imgpeak - tpcclib 0.8.0 © 2023 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.
