imginteg 1.3.3 © 2005-2013 by Turku PET Centre
Calculation of an AUC (integral over time) image from PET image
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 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.
Command line arguments:
1) PET image
2) AUC calculation start time (sec)
3) AUC calculation duration (sec)
4) AUC image file
Options:
-avg
Average during specified range is calculated instead of AUC
-min
AUC times are given in minutes instead of seconds
-h or --help
Print this message and exit
--version or --build
Print software build information and exit
--silent
Program works silently, printing only error and warning messages
--verbose
Program prints more information about what it is doing.
Program will automatically set the integration start time or duration
based on the time range in the image, if either is set to zero.
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
