imginteg - tpcclib 0.7.5 © 2020 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.
 
Options:
 -avg
     Average during specified range is calculated instead of AUC.
 -min
     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
