Figure 22

An example of an assembled ‘thick’ slab detector. A 50 × 50 × 8 mm3 LYSO crystal is mounted on a 64-anode PMT. A statistical estimation approach is used to provide a spatial resolution of ~1.4 mm and at least 2 bits of DOI information. Several investigators are working to use thicker slabs and improve both the spatial resolution and DOI capabilities of such designs.
