Siemens' MR-PET prototype is dedicated to the brain and the PET scanner USES a next-generation Avalanche Photodiode Detector (APD) technology.
西门子的MR - PET样机致力于大脑，PET扫描应用了新一代雪崩光电探测器(APD)技术。

The avalanche photodiode detector is followed by a front-end amplifier and equalizer or filter to provide gain as well as linear signal processing and noise bandwidth redution.
前置放大器与均衡器或滤波器跟在雪崩二极管检测器的后面以获得增益，线性信号处理及噪声宽带的抑制。
