ecattime

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.
