SilverRay Ltd is a start-up company whose primary goal is to exploit a proprietary technology developed for the production of large area, high sensitivity X-ray detectors for real-world applications. This proprietary technology has demonstrated a 2-3 orders of magnitude higher X-ray detection sensitivity than conventional organic detectors, whilst operating at low voltages and offering excellent shaping to complex surfaces. Further, the technology has detected X-radiation over a broad energy range, from 60 kV to 6 MV, making it applicable for a variety of end applications such as medical radiography, non-destructive testing, and security border controls, amongst others.The current, dominant technology for non-destructive testing (NDT) by radiography is the use of advanced digital X-ray imaging technology based on inflexible flat panel detectors, with outputs displayed directly on to a computer screen. The detectors cannot be flexed, and need to be used in its rigid form with care due to its high expense and fragility. This is in comparison to the traditional and widely used flexible photographic film technology which allows access to complex parts/corners of an object but which does not offer real-time imaging or digital manipulation.At SilverRay Ltd, we have developed a detector active material consisting of a printable 'X-ray sensitive ink' containing two elements: an interpenetrating network of organic material and inorganic nanoparticles. The 'X-ray sensitive ink' can be used to coat X-ray sensitive pixelated films over a wide range of substrates, including the development of flexible detectors.Thus far, small area detectors (<1 cm2) have been successfully developed by SilverRay Ltd. The aim of the current project is to scale up the technology to large area (8x2.5 cm2) conformable, multi-pixel, digital devices suitable for X-ray imaging in NDT applications. Readout electronics will be developed allowing for remote NDT examination in a manufacturing setting. With the project collaborator, Tata Steel, detector performance will be tested in a real world application on safety critical products used in the construction industry.The X-ray imaging system produced as an outcome of this feasibility programme will allow SilverRay to demonstrate their proprietary large area digital film based technology at a scale suitable for many other applications including NDT. This novel breakthrough technology is backed by a US granted patent application, and will be initially adopted to manufacture detectors suitable for NDT applications such as for the safety critical products identified here.

SilverRay有限公司是一家初创公司，其主要目标是开发一项专有技术，用于生产用于现实世界应用的大面积、高灵敏度X射线探测器。这项专利技术已经证明，X射线检测灵敏度比传统的有机探测器高2-3个数量级，同时工作在低电压下，并为复杂表面提供出色的成形。此外，该技术已在从60千伏到6兆伏的广泛能量范围内检测到X射线辐射，使其适用于各种终端应用，如医疗射线照相、无损检测和安全边界控制等。目前，射线照相无损检测(NDT)的主导技术是使用基于刚性平板探测器的先进数字X射线成像技术，输出直接显示在计算机屏幕上。探测器不能弯曲，由于其高成本和易碎性，需要以刚性形式小心使用。这与传统和广泛使用的柔性摄影胶片技术相比，这种技术允许进入对象的复杂部分/角落，但不提供实时成像或数字操作。在SilverRay Ltd，我们开发了一种探测器活性材料，由可打印的“X射线敏感墨水”组成，其中包含两种元素：有机材料和无机纳米颗粒的互穿网络。X光敏感油墨可用于在多种衬底上涂覆X光敏感像素化薄膜，包括柔性探测器的开发。到目前为止，SilverRay有限公司已成功开发出小面积探测器(&lt；1 cm2)。当前项目的目标是将该技术扩大到适用于无损检测应用中的X射线成像的大面积(8x2.5 cm2)兼容、多像素数字设备。将开发读出电子设备，以便在制造环境中进行远程无损检测检查。与项目合作者塔塔钢铁公司合作，探测器性能将在建筑行业使用的安全关键产品的真实应用中进行测试。作为这一可行性计划的结果而生产的X射线成像系统将使SilverRay能够展示其专有的基于大面积数字胶片的技术，其规模适用于许多其他应用，包括无损检测。这项新颖的突破性技术得到了一项美国授权专利申请的支持，最初将被用于制造适用于无损检测应用的探测器，例如这里确定的安全关键产品。
