title: The challenge of detector designs for PET.
abstract: OBJECTIVE
  The use of PET, especially the use of PET/CT scanners, has expanded rapidly over the past few years. Although most of the detector development efforts have been focused on scintillator-based designs, other technologies, such as wire chambers, time projection chambers, and solid-state devices, are also being pursued.
  
  
  CONCLUSIONS
  Many of these new technologies have not translated into commercial systems. This article will explore some of the basic challenges of PET detector designs.
