    • An X-ray sensitive coating (22) for a flat panel direct conversion X-ray detector for medical or industrial imaging. A composite particle-in-binder (PIB) material (22) may contain X-ray photoconductive particles (23) such as PbO (lead monoxide) in a binder of polyimide (23). This PIB material may be prepared in precursor paste form, and applied as a coating (22) onto a thin film transistor array (26) having a storage capacitor (31) at each pixel (30). The coating (22) is cured, and an electrically conducting layer (34) is applied to the exposed surface of the coating (22), to provide a bias voltage. X-ray photons striking the photoconductive particles (23) cause localized electrical conduction proportional to the number of photons. This charges respective capacitors (31) that provide image data input to a computer.
    • 用于医疗或工业成像的平板直接转换X射线检测器的X射线敏感涂层(22)。 复合粒子 - 粘合剂(PIB)材料(22)可以在聚酰亚胺(23)的粘合剂中含有X射线光电导颗粒(例如PbO(一氧化铅))。 该PIB材料可以以前体浆料形式制备,并作为涂层(22)施加到在每个像素(30)处具有存储电容器(31)的薄膜晶体管阵列(26)上。 固化涂层(22),并且将导电层(34)施加到涂层(22)的暴露表面,以提供偏置电压。 撞击光导电颗粒(23)的X射线光子引起与光子数成比例的局部电传导。 这样,向计算机提供输入图像数据的各个电容器(31)。
