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.　Apartment　from　a　historical　overview　of　the　develop-X-ray　direct　imaging　detectors　and　their　performance　indicators,　this　review　specifically　focuses　on　the　development,　innovation,　and　utilization　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.　image
