基于康普顿过程的完全重建的MeV γ射线成像相机的原型已经开发。该相机由微型TPC（气体时间投影室（TPC））和闪烁相机组成。利用反冲电子和散射γ射线的信息，该相机检测每个入射γ射线的能量和入射方向。我们开发了一个原型的MeV γ射线相机与微型TPC和NaI（Tl）闪烁体，并成功地重建γ射线从0.3至1.3 MeV。对于356 keV γ射线，测量的ARM（角分辨率测量）和SPD（散射平面偏差）的角分辨率分别为18度和35度。(c)2005 Elsevier B.V.保留所有权利。
A prototype of the MeV gamma-ray imaging camera based on the full reconstruction of the Compton process has been developed. This camera consists of a micro-TPC that is a gaseous Time Projection Chamber (TPC) and scintillation cameras. With the information of the recoil electrons and the scattered gamma-rays, this camera detects the energy and incident direction of each incident gamma-ray. We developed a prototype of the MeV gamma-ray camera with a micro-TPC and a NaI(Tl) scintillator, and succeeded in reconstructing the gamma-rays from 0.3 to 1.3 MeV. Measured angular resolutions of ARM (Angular Resolution Measure) and SPD (Scatter Plane Deviation) for 356 keV gamma-rays were 18 degrees and 35 degrees, respectively. (c) 2005 Elsevier B.V.
