imginteg - tpcclib 0.8.0 © 2023 by Turku PET Centre

Calculates AUC (integral over time) image from PET image in
in ECAT 6.3, 7.x, NIfTI-1, or Analyze 7.5 format.
Analyze and NIfTI image must have SIF in the same folder.
In case of a static image, the matrix values are simply multiplied by the
frame duration.
The pixel values of resulting integral image will be in units of
radioactivity concentration times sec.
Usage: imginteg [Options] image starttime duration aucimage
AUC start time and duration (not stop time) must be entered in seconds;
program will automatically set the integration start time or duration
based on the time range in the image, if either is set to zero.
     Average during specified range is calculated instead of AUC.
     AUC times are given in minutes instead of seconds.
 -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.
Example 1: calculate integral image between 32 and 302 seconds after
scan start with command
  imginteg s5998dy1.v 32 270 s5998int.v
Example 2: integrate a static or dynamic image from the start time of
the first frame to the end of the last frame:
  imginteg a773dy1.v 0 0 a773int.v
Example 3: integrate a dynamic image from 600 seconds to the end of
the last frame:
  imginteg a773dy1.v 600 0 a773int.v
