利用原子级缺陷作为最小发光单元，如银激活磷酸盐玻璃中的辐射诱导银（Ag）相关物质，开发了新型盘型X射线二维和三维（2D，3D）剂量分布。这种发光探测器是基于辐射光致发光（RPL）现象。准确的累积剂量分布与高空间分辨率的数量级微米以上的大面积，一个宽的动态范围，涵盖三个数量级和非破坏性的读出首次成功地证明了通过使用盘型玻璃板与100毫米的直径和1毫米的厚度。此外，共焦光学检测系统与透明玻璃检测器的组合通过在材料内不同深度处堆积每个剂量图像来实现3D重建。
Novel disk-type X-ray two-and three-dimensional (2D, 3D) dose distributions have been developed using atomic-scale defects as minimum luminescent units, such as radiation-induced silver (Ag)-related species in a Ag-activated phosphate glass. This luminescent detector is based on the radiophotoluminescence (RPL) phenomenon. Accurate accumulated dose distributions with a high spatial resolution on the order of microns over large areas, a wide dynamic range covering three orders of magnitude and a non-destructive readout were successfully demonstrated for the first time by using a disk-type glass plate with a 100-mm diameter and a 1-mm thickness. In addition, the combination of a confocal optical detection system with a transparent glass detector enables 3D reconstruction by piling up each dose image at different depths within the material.
