Description

Recently, the development of combined TEP/CT imaging systems led to a rapid expansion of this technique in clinical routine. Like for clinical routine, the development of dedicated PET scanners and micro- CT scanners for small animals encourages to have these two imaging modalities embedded on a common gantry. However, the juxtaposition of both modalities does not allow for extrapolating exact position of the animal during the PET scan. Therefore, we intend to combine phoswich detector modules developed for the ClearPET small animal PET scanners with hybrid pixel detectors developed for the small animal PIXSCAN micro-CT scanner in a common rotating gantry to study simultaneous TEP/CT hybrid imaging. Ultimately, the use of hybrid X and gamma detector modules capable to detect simultaneously X rays and gamma rays would allow for developing new methods to correct PET data for the animal movements due to respiration or cardiac motion by using transmission data correlated with physiologic signals.
