ecattime 2.0.3 © 2002-2012 by Turku PET Centre

Changes the scan start and frame times in PET image or sinogram file in ECAT 6.3 or 7 format to refer to the injection time instead of the original delayed scan start time. Correction for physical decay is changed accordingly in images, but not in sinograms. Before using this program, PET image must be decay corrected to its scan start time, but sinogram must not be corrected for decay. Please note that file may be changed, but backup file is not made. Usage: ecattime [Options] <ECAT image or scan filename> [Time] 'Time' is either the time (min) from radiotracer injection to the PET scan start time, or, the new scan start time. If 'Time' is not entered, then program makes no changes to the data, but only displays the current scan start time and time when the collection of the first frame was started. Options: -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. Example 1. PET scan is known to have started 30.2 min after tracer injection. Times and decay will be corrected to the new scan start time: ecattime s2345dy1.v 30.2 Example 2. Injection time was 14:00:49, and PET times and decay will be corrected to this new scan start time: ecattime s2345dy1.v 14:00:49 See also: edecay, eframe, egetstrt, ecatunit Keywords: ECAT, image, physical decay, modelling This program comes with ABSOLUTELY NO WARRANTY.
