Abstract

Newly developed copper-iodide cluster microcubes offer a solution to the issues commonly faced by powder scintillation screens. These problems include inadequate scintillation performance and significant light scattering, resulting in poor image quality. With the advent of monodisperse copper-iodide cluster microparticle scintillators, efficient and long-term stable scintillation is achieved, while ensuring biocompatibility. Moreover, they enable high-resolution static and dynamic X-ray imaging, providing high image quality.

摘要

新开发的碘化铜簇微立方体为粉末闪烁屏常见的问题提供了解决方案。这些问题包括闪烁性能不足和严重的光散射,导致图像质量较差。随着单分散碘化铜簇微粒闪烁体的出现,实现了高效且长期稳定的闪烁,同时确保了生物相容性。此外,它们能够实现高分辨率的静态和动态X射线成像,提供高质量的图像。
