Title
(EN) Flat panel detector and manufacturing method thereof
(ZH) 平板探测器及其制造方法
Abstract
(EN) The invention discloses a flat panel detector and a manufacturing method thereof. The flat panel detector includes a first optical assembly having a first side and a second side along a thickness direction of the flat panel detector, and also includes a first scintillator layer for converting at least a portion of rays into first visible light and a first light conduction structure stacked with the first scintillator layer, and the first scintillator layer is used for conducting the first visible light. The flat panel detector further comprises a first image sensor assembly which is stacked with the first optical assembly and used for receiving the first visible light, and the first image sensor assembly comprises a first image sensor and a second image sensor which are located on the first side and the second side of the first optical assembly respectively. By arranging the second image sensor, part of the first visible light emitted from the upper surface of the first scintillator layer can reach the second image sensor for imaging, and loss caused by propagation of the first visible light in the first scintillator layer is avoided.
(ZH) 公开了一种平板探测器及其制造方法。该平板探测器包括第一光学组件,所述第一光学组件具有沿所述平板探测器的厚度方向的第一侧和第二侧并且包括:第一闪烁体层,用于将至少部分射线转化为第一可见光和第一光传导结构,与所述第一闪烁体层堆叠,用于传导所述第一可见光。该平板探测器还包括第一图像传感器组件,与所述第一光学组件堆叠,用于接收所述第一可见光,所述第一图像传感器组件包括:分别位于所述第一光学组件的所述第一侧和所述第二侧的第一图像传感器和第二图像传感器。通过设置第二图像传感器,使从第一闪烁体层的上表面出射的部分第一可见光能够抵达第二图像传感器成像,避免了第一可见光在第一闪烁体层内传播导致的损失。
