“…To optimally use these pixels, newer generation scintillation crystals are segmented into into small pixel arrays. There are now a multitude of PET camera heads [1,2,3] The common feature of these instruments is that there is a very fine two-dimensional square pixellization, typically 2 to 4 mm a side, and an unpixellized third dimension. As the size of the pixels shrinks, the cost in generating these crystals grows, and the fraction of the area taken up by gaps between the crystals grows significantly.…”

We have demonstrated a PET imaging system based on double-sided germanium strip detectors. The demonstration achieved an intrinsic position resolution of 1.35 mm FWHM. This performance was achieved with 2 mm orthogonal strips and a depth sensing capability of 0.5 mm based on timing the pulses at either side of the detector. The system could trigger at energies as low as 15 keV without any image degradation. By selecting events within the 2 keV-wide photopeak, events that scattered within the sampling volume were totally eliminated. If a detector is built with 1 mm strips, the position resolution for PET imaging will not be dominated by the position resolution of the instrument, but by the range of the positron in the sample.

The performance of a position sensitive gamma-ray scintillator detector (PSD) is described. This PSD is based on a lutetium yttrium oxyorthosilicate (LYSO) crystal read out by a crossed-wire anode position sensitive photomultiplier tube (PSPMT). The main difference with respect to similar existing devices is the individual multi-anode readout (IMAR) approach that is followed here. This method allows to exploit better the intrinsic characteristics of the PSPMT, thus yielding better linearity, improved spatial resolution, and a larger field of view. The new detector is intended for the characterization of 3-D position sensitive germanium detectors.
