| 英文摘要 | In this work we studied the feasibility of detecting the depth of interaction (doi) with two layers of crystal arrays of lyso and bgo scintillators coupled to a position-sensitive photomultiplier tube (ps-pmt) r8900-c12. a front-end electronics was designed, with which we got different pulse shapes for different crystals to obtain depth information. with the double integration method, we got the doi histogram of a divided integration ratio of two crystals as the standard to determine the layer-of-interaction. the doi accuracy, measured by scanning a (22)na slit source along the side of the module, was 98% for the lyso layer and 95% for the bgo layer. the energy resolution at 511kev was 13.1% for lyso and 17.1% for boo. we obtained good crystal separation in 2d position histograms of both layers. these results could be useful in the manufacture of pet scanners with high spatial resolutions. |
