In order to establish a novel method for a neuronal activity-dependent neuroimaging analysis, a non-metal imaging device was fabricated to record the neurophysiological changes and PET scans simultaneously. The numerical model-based attenuation correction was implemented to correct for the lower counts induced by the device. The radioactivity in the blood quickly achieved a steady state after the intravenous injection of FDG combining bolus injection and continuous infusion, whereas it was continuously increased in the brain. Moreover, the electrical stimulation-related functional neuroimages were reconstructed by a trigger driven gating method in which every 5-sec PET list mode data were sorted into a gate sinogram according to a time-stamp driven by a trigger signal which was synchronized with the electrical stimulation.

为了建立一种新的神经元活动依赖的神经影像分析方法，我们制作了一种非金属成像装置，可以同时记录神经生理变化和PET扫描。 实施基于数值模型的衰减校正，以校正器械引起的较低计数。 静脉注射FDG结合快速推注和持续输注后，血液中的放射性迅速达到稳定状态，而脑中的放射性持续增加。 此外，通过触发驱动门控方法重建与电刺激相关的功能神经图像，其中每5秒PET列表模式数据根据与电刺激同步的触发信号驱动的时间戳被分类到门控正弦图中。
