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]
Save a template image containing the frame numbers (1..frame_nr)
where the maximum pixel values were found.
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.
Save the peak time (sec) of each pixel (middle time of peak frame).
Save the peak time (sec) of each pixel, calculated as weighted
average of 3 or 5 subsequent frames.
Save the value-weighted mean time (sec) of all frames.
Mean residence time (MRT) in PK for PTACs uses the same equation.
Use only pixels with peak value above (threshold/100 x max peak);
default is 5%.
Maximum pixel values are divided by the frame average.
