Thresholding of dynamic PET image in ECAT 6.3 or 7.x format. Akaike information criteria is used to determine whether the TAC of a single pixel consists of noise only. If no significant signal is found, that pixel is set to zero. After this operation, PET data can usually be compressed to about one-third of the original file size. Usage: ebkgrm <Image file> <Thresholded image file> [Template file] Options: -RN Also sets to zero pixels which have AUC<0 Optional template file will contain pixel values 0 (removed pixels) and 1 (conserved pixels).
