"This project will deliver a proof of concept for a ground-breaking medical imaging system for hands and feet. Fractures of these are common but the current imaging methods are unsatisfactory. Standard X-rays only give a 2D view (i.e. a shadow) of these complex 3D joints and subtle fractures or problems can be missed. CT and MRI scanners produce 3D images but are expensive, time-consuming and often immovable, and CT scans involve a relatively high radiation dose. Our proposed product will provide 3D images from a low cost, low dose, portable device. No current device on the market offers this.Adaptix will achieve this by fundamentally changing how X-rays are made. Conventional X-ray tubes haven't changed significantly in a century whilst televisions have changed from CRT tubes to flat screens and bulbs from filaments to arrays of LEDs. Adaptix's innovative technology makes a similar technological leap for X-ray sources. Instead of a single, high-power source of X-rays, we use solid state technology to create an array of many emitters arranged in a lightweight flat panel with low power consumption. The panel illuminates the patient from a variety of angles so can use parallax information to derive 3D information (a technique called tomosynthesis), in the same way that having more than one eye gives us depth perception. This is done at a radiation dose much less than CT.This project will take Adaptix's core technology and refine its use for imaging hands and feet. This will involve modifying the X-ray source to optimize its performance for these and elaborating requirements and designs with orthopaedic doctors. These outputs will confirm that the technology is viable and that the product will meet the market needs."

“该项目将为突破性的手部和脚部医学成像系统提供概念验证。这些骨折是常见的，但目前的成像方法是不满意的。标准X射线只能提供这些复杂3D关节的2D视图（即阴影），可能会错过细微的骨折或问题。CT和MRI扫描仪产生3D图像，但昂贵，耗时且通常不可移动，并且CT扫描涉及相对较高的辐射剂量。我们提出的产品将从低成本、低剂量、便携式设备提供3D图像。目前市场上还没有这样的设备，Adaptix将通过从根本上改变X射线的制造方式来实现这一目标。传统的X射线管在一个世纪里没有发生重大变化，而电视机已经从CRT管变成了平板屏幕，灯泡从灯丝变成了LED阵列。Adaptix的创新技术为X射线源带来了类似的技术飞跃。我们使用固态技术来创建一个由许多发射器组成的阵列，而不是一个单一的高功率X射线源，这些发射器排列在一个重量轻、功耗低的平板上。该面板从各种角度照亮患者，因此可以使用视差信息来获得3D信息（一种称为断层合成的技术），就像拥有多只眼睛给我们带来深度感知一样。该项目将采用Adaptix的核心技术，并将其用于手脚成像。这将涉及修改X射线源，以优化其性能，并与骨科医生一起制定要求和设计。这些产出将证实技术是可行的，产品将满足市场需求。"
