Positron emission tomography (PET) detection modules consist of pixelated scintillator crystals optically coupled to position sensitive photomultiplier tubes (PS-PMT). This type of modules should be able to provide sufficient spatial resolution for animal PET applications. We have characterised a Hamamatsu H6568 multianode PS-PMT. Anode uniformity was obtained by illuminating, via an optical fiber, individual anodes with light pulses from an LED. Using a 4x4 pixelated LYSO crystal, each of 2x2x15 mm3, and a {sup 137}Cs radioactive source, the light spread function was obtained. This work forms part of the construction of a microPET system at the Institute of Physics, UNAM.
