    • A scintillator element (114) comprising uncured scintillator material (112) is formed and optically cured to generate a cured scintillator element (122, 122″). The uncured scintillator material suitably combines at least a scintillator material powder and an uncured polymeric host. In a reel to reel process, a flexible array of optical detectors is transferred from a source reel (100) to a take-up reel (106) and the uncured scintillator material (112) is disposed on the flexible array and optically cured during said transfer. Such detector layers (31, 32, 33, 34, 35) are stackable to define a multi-layer computed tomography (CT) detector array (20). Detector element channels (50, 50′, 50″) include a preamplifier (52) and switching circuitry (54, 54′, 54″) having a first mode connecting the preamplifier with at least first detector array layers (31, 32) and a second mode connecting the preamplifier with at least second detector array layers (33, 34, 35).
    • 形成包括未固化的闪烁体材料(112)的闪烁体元件(114)并光学固化以产生固化的闪烁体元件(122,122“)。 未固化的闪烁体材料适当地组合至少闪烁体材料粉末和未固化的聚合物主体。 在卷轴到卷轴过程中,光学检测器的柔性阵列从源卷轴(100)传送到卷取卷轴(106),并且未固化的闪烁体材料(112)设置在柔性阵列上并且在所述 转让。 这种检测器层(31,32,33,34,35)可堆叠以限定多层计算机断层摄影(CT)检测器阵列(20)。 检测器元件通道(50,50',50“)包括前置放大器(52)和具有将前置放大器与至少第一检测器阵列层(31,32)连接的第一模式的开关电路(54,54',54”),以及 连接前置放大器与至少第二检测器阵列层(33,34,35)的第二模式。
