A method for estimating randoms in PET imaging data includes acquiring imaging data that includes a plurality of singles and a plurality of randoms, where the randoms exhibit a non-exponential decay, generating a randoms correction estimate based on the non-exponential decay, and applying the randoms correction estimate to the imaging data to generate corrected imaging data. The method further includes generating an image using the corrected image data. An imaging system and computer readable medium programmed to estimate randoms is also provided.
