Temperature dependence of the LabPET small-animal PET scanner [PDF]
2012 IEEE Nuclear Science Symposium and Medical Imaging Conference Record (NSS/MIC), 2012 INTRODUCTION In quantitative PET imaging it is important to correct for all image-degrading effects, for example detector efficiency variation. Detector efficiency variation depends on the stability of detector efficiency when operating conditions vary within normal limits.

Improved dead-time correction for PET scanners: application to small-animal PET [PDF]
Physics in Medicine and Biology, 2013 Pile-up and dead-time are two main causes of nonlinearity in the response of a PET scanner as a function of activity in the field of view (FOV). For a given scanner and acquisition system, pile-up effects depend on the material and size of the object being imaged and on the distribution of activity inside and outside the FOV, because these factors ...
