High spatial resolution in a positron tomograph with multislice imaging capability can be achieved by some form of position encoding to avoid the complexity resulting from individual photomultipliers (PMT) coupled to individual small crystals. The authors recently completed a multislice positron tomograph using six large area NaI (T1) crystals coupled to 50-mm square PMTs, which results in a large number of resolution elements with relatively low complexity compared to other approaches. The design and performance of this instrument, which is based on a previously constructed single-slice version, is described in this paper, emphasizing those aspects which differ from other designs.
