MeV γ射线成像已成为许多领域，特别是医学领域不可或缺的技术。然而，由于其固有的困难，MeV伽马射线的完整射线追踪尚未实现。准直是一种常规的准成像方法，目前已用于SPECT，但其成像质量并不令人满意。康普顿方法提供了射线追踪所需的两个方向之一，目前仍在开发中。探测伽马射线对方向的唯一方法是PET，由于其成本高和同位素有限，其使用受到限制。一个完整的射线追踪单光子伽马射线相机将给我们带来核医学的巨大进步。本文报道了一种新的方法和仪器，它不仅实现了康普顿过程的完全再现，而且利用新型微跟踪装置提供了强的背景抑制
MeV gamma-ray imaging has become an indispensable technology in many fields, especially medical science. A full ray-tracing of MeV gamma-rays, however, has not been realized because of its intrinsic difficulty. Collimation is one of the conventional quasi-imaging methods and is used in SPECT, although the quality of the image is not satisfying. The Compton method, which provides one of the two directions required for the ray-tracing, is still under development. The only method to detect the direction of a gamma-ray pair is PET, the use of which is restricted because of its high cost and limited isotopes. A full ray-tracing gamma-ray camera for single photons would give us great advances in nuclear medicine. Here we report on the new method and instrument, which has not only realized a complete reconstruction of the Compton process but also provided a strong background-rejection with the novel micro-tracking device
