Metal halide perovskites (MHP) have demonstrated excellent X-ray detection performance, thanks to their compelling properties including large mobility-lifetime product, strong X-ray absorption, and easy synthesis, etc. The latest progress and future perspective of MHP-based X-ray detection and imaging are reviewed herein. The fundamental knowledge of X-ray interaction with materials and the characteristics of direct and indirect (via scintillators) X-ray detection is first discussed. We then introduce the methods for scalable fabrication of MHP and summarize their recent device performance. We further present the integration of MHP detectors with readout integrated circuits and the associated performance metrics for flat panel detector (FPD). We also briefly talk about ways to minimize cross-talk and increase spatial resolution in FPDs. Last, we provide some cautions to evaluate the detector performance and some suggestions to further improve the performance. We hope this paper can help readers understand the status and future challenges for perovskite X-ray detectors.

金属卤化物钙钛矿（MHP）具有出色的X射线检测性能，这要归功于其引人注目的特性，包括较大的可移动寿命产品，强的X射线吸收性和易于合成的特性等。射线检测和成像在本文中进行了回顾。首先讨论了X射线与材料相互作用的基本知识以及直接和间接（通过闪烁体）X射线检测的特性。然后，我们介绍了可扩展制造MHP的方法，并总结了它们最近的设备性能。我们进一步介绍了MHP检测器与读出集成电路的集成以及平板检测器（FPD）的相关性能指标。我们还将简要讨论如何在FPD中最小化串扰并提高空间分辨率。持续，我们提供一些注意事项以评估检测器性能，并提供一些建议以进一步提高性能。我们希望本文能够帮助读者了解钙钛矿X射线探测器的现状和未来的挑战。
