我们正在开发HelmetPET，这是一种可穿戴的人类PET脑成像仪，它具有在站立、平衡或移动患者时利用基于PET的放射性药物评估脑功能的潜在应用。HelmetPET由两个辐射探测器环组成，一起提供轴向长度为5厘米的圆柱形重建体积。每个环由20个基于2.5cm2硅光电倍增管(SiPM)的探测器模块组成。每个探测器模块由25个滨松S10362-33-050P多像素光子计数器(MPPC)的5×5阵列组成。3mm2的MPPC排列在5 mm的台阶上。耦合到每个MPPC模块的是耦合到MPPC阵列的LYSO闪烁体晶体阵列，该阵列使用两个不同的LYSO像素阵列：1.0×1.0×10 mm~3和1.5×1.5×10 mm~3。该项目的当前阶段是为40个2.5平方厘米的探测器模块配备电阻读数，并将其组装在头盔式磁头支架中，然后悬挂在灵活的机械安装架上。
We are developing the HelmetPET, a wearable human PET brain imager which has the potential application of evaluating brain function utilizing PET based radiopharmaceuticals in standing, balancing or moving patients. The HelmetPET is composed of two rings of radiation detectors together providing a cylindrical reconstructed volume with an axial length of 5 cm. Each ring is composed of twenty 2.5 cm2 silicon photomultiplier (SiPM) based detector modules. Each detector module is composed of a 5×5 array of twenty-five Hamamatsu S10362-33-050P Multi Pixel Photon Counters (MPPCs). The 3 mm2 MPPCs are arranged on a 5mm step. Coupled to each of the MPPC modules is a LYSO scintillator crystal array coupled to the MPPC array using to two different LYSO pixel arrays: 1.0×1.0×10 mm3 and 1.5×1.5×10 mm3. The current phase of the project is to equip the forty 2.5 cm2 detector modules with resistive readout and assemble them in a helmet type head support and suspend from a flexible mechanical mount.
