摘要： Improved imaging systems are disclosed. More particularly, the present disclosure provides for an improved image sensor assembly for an imaging system, the image sensor assembly having an integrated photodetector array and its associated data acquisition electronics fabricated on the same substrate. By integrating the electronics on the same substrate as the photodetector array, this thereby reduces fabrications costs, and reduces interconnect complexity. Since both the photodiode contacts and the associated electronics are on the same substrate/plane, this thereby substantially eliminates certain expensive/time-consuming processing techniques. Moreover, the co-location of the electronics next to or proximal to the photodetector array provides for a much finer resolution detector assembly since the interconnect bottleneck between the electronics and the photodetector array is substantially eliminated/reduced. The co-location of the electronics next to or proximal to the photodetector array also enables/facilitates programmable pixel configuration for optimal image quality.
摘要翻译：公开了改进的成像系统。更具体地，本公开提供了一种用于成像系统的改进的图像传感器组件，该图像传感器组件具有集成的光电检测器阵列及其在相同基板上制造的相关联的数据采集电子装置。通过将电子元件集成在与光电检测器阵列相同的基板上，由此降低了制造成本，并降低了互连复杂度。由于光电二极管触点和相关联的电子器件都在相同的衬底/平面上，因此基本上消除了某些昂贵/耗时的处理技术。此外，由于电子设备和光电检测器阵列之间的互连瓶颈基本上被消除/减少，所以电子器件靠近光电检测器阵列的共同定位提供了更精细的分辨率检测器组件。靠近或接近光电检测器阵列的电子设备的共同位置也使得/促进可编程像素配置以获得最佳图像质量。

摘要： Transparent optical ceramic coating materials have been fabricated from europium-doped lutetium oxide (Lu2O3:Eu) using physical vapor deposition and chemical vapor deposition techniques. The non-pixilated film coatings have columnar microcrystalline structure and excellent properties for use as radiological scintillators, namely very high density, high effective atomic number, and light output and emission wavelength suitable for use with silicon-based detectors having a very high quantum efficiency. The materials can be used in a multitude of high speed and high resolution imaging applications, including x-ray imaging in medicine.
