For whole-body CT images of small rodents, a voxel resolution of at least 10(-3) mm(3) is needed for scale-equivalence to that currently achieved in clinical CT scanners (∼1 mm(3)) in adult humans. These "mini-CT" images generally require ...

Simple theory predicts that the statistical noise variance in PET can be reduced by an order of magnitude by using time-of-flight (TOF) information. This reduction can be obtained by improving the coincidence timing resolution, and so would...
