| 内容記述 | Previously, we proposed an 8-layer depth-of- interaction (DOI) encoding method for a PET detector and proved its validity. The layer of interaction is identified by hybrid method; the scintillation light control by the original reflector arrangement for 4-layer DOI encoding and the pulse shape discrimination for 2-layer DOI encoding. Four layers then consist of the scintillator of different pulse shape from the scintillator for the other four layers. We investigated the effect of crystal arrangement difference on detector performance to optimize the DOI detector. The two kind layers can be arranged in two ways; stacked alternately or set in the upper and lower four layers respectively. Since the two crystal arrangements are supposed to show different detector performance, we measured it on each arrangement. The results show better performance of the stacked arrangement in pulse shape discrimination, while inferior in crystal identification among the same kind scintillation crystals composing four layers. There was no particular difference between the two crystal arrangements in light outputs and energy resolutions of each layer. |
