Abstract
Abstract This review discusses the utilization of metal halide perovskite (MHP) materials in X‐ray direct imaging detectors for medical application. Compared to traditional semiconductors, MHP has multiple advantages including high linear attenuation coefficient, low exciton binding energy, long carrier diffusion length, and high carrier mobility. These ascendancies allow for low‐dose and high‐resolution medical imaging. Apartment from a historical overview of the develop‐X‐ray direct imaging detectors and their performance indicators, this review specifically focuses on the development and innovation of X‐ray direct imaging detectors using MHP materials. The article concludes by identifying existing challenges and discussing the potential application of perovskite X‐ray direct imaging detectors in the medical industry.
