摘要:

TT-PET合作正在开发一种用于小动物的PET扫描仪,具有30 ps的飞行时间分辨率和亚毫米级3D检测粒度。扫描仪的敏感元件是基于最先进的SiGe BiCMOS技术的单片硅像素检测器。TT-PET的第一个ASIC原型是在实验室中生产和测试的,电离粒子最少。根据模拟,电子器件表现出低于600 e-RMS的等效噪声电荷和小于2 ns的脉冲上升时间。具有0.8pF电容的像素被测量为具有大于99%的检测效率,并且尽管在不存在后处理的情况下,具有大约200 ps的时间分辨率。

英文摘要:

The TT-PET collaboration is developing a PET scanner for small animals with 30 ps time-of-flight resolution and sub-millimetre 3D detection granularity. The sensitive element of the scanner is a monolithic silicon pixel detector based on state-of-the-art SiGe BiCMOS technology. The first ASIC prototype for the TT-PET was produced and tested in the laboratory and with minimum ionizing particles. The electronics exhibit an equivalent noise charge below 600 e- RMS and a pulse rise time of less than 2 ns, in accordance with the simulations. The pixels with a capacitance of 0.8 pF were measured to have a detection efficiency greater than 99% and, although in the absence of the post-processing, a time resolution of approximately 200 ps.
