摘要： A light-reflecting material of a radiation detector, which also comprises photo-detecting elements and imaging elements adjacent to the photo-detecting elements, is provided. Typically, epoxy resin is used as the light-reflecting material. A tough, pliable resin may be used for the photo-detecting elements. This has the advantage of reducing thermal stresses inside the radiation detector, thus reducing the risk of delamination due to e.g. temperature shifts. Moreover, the tough, pliable resin preferably also has a low refractive index, which may increase the scattering co-efficient of the resin as compared to epoxy resin, which has a refractive index of 1.58. The layer thickness of a low-refractive index resin may thereby be reduced as compared to the layer thickness of epoxy resin for a given level of optical crosstalk. Preferable resins are silicon resins and resins of thermoplastic fluoropolymers.
摘要翻译：提供了一种辐射检测器的光反射材料，其还包括光检测元件和与光检测元件相邻的成像元件。通常，使用环氧树脂作为光反射材料。光敏元件可以使用韧性柔韧的树脂。这具有降低辐射检测器内的热应力的优点，从而降低由于例如温度而导致的分层的风险。温度变化。此外，与折射率为1.58的环氧树脂相比，韧性柔韧的树脂优选还具有低折射率，这可以增加树脂的散射系数。因此，与给定光学串扰水平的环氧树脂的层厚度相比，低折射率树脂的层厚可以减小。优选的树脂是硅树脂和热塑性含氟聚合物的树脂。

摘要： 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).
