AX-PET - A Demonstrator for an Axial PET Camera with WLS Strips and G-APD Readout

The image shows the reconstruction of different sections of a NEMA-IQ-Mouse-Phantom (see PetPhantoms). Data taken in measurement campaign during July 2011 at AAA (Saint Genis Pouilly, France).

What's special about AX-PET ?

AX-PET is a novel PET detector based on long axially arranged crystals and orthogonal Wavelength shifter (WLS) strips, both individually readout by Geiger-mode Avalanche Photo Diodes (G-APD, also called SiPM). Its design was conceived to reduce the parallax error and simultaneously improve spatial resolution and sensitivity. A 'Demonstrator' has been built which consists of 2 detector modules (in total 96 LYSO crystals and 312 WLS strips). After extensive tests in the lab with Na-22 point sources, the Demonstrator was characterized with phantoms at the small animal PET lab at ETH Zurich (link) and the company AAA in France. Recently, in spring 2012, we successfully demonstrated imaging with F-18 and FDG of mice and rats.
