"Almost everyone will have had a dental X-ray. These help dentists make informed decisions about diagnoses and treatments. However, each X-ray is just a 2D shadow of a 3D shape so assessing the size and shape of feature such as cavities in teeth can be difficult. Large 3D imaging systems do exist today but they are expensive, only available at specialist centres and they give a relatively high radiation dose.Adaptix has a new method of obtaining 3D X-ray data. Adaptix have miniaturised the X-ray emitter meaning that many emitters can be arranged in flat panel array. Electronically firing X-rays from 45 different positions means that 3D information can be derived, in the same way that having 2 eyes in different positions gives us depth perception. Adaptix's device is small enough to be used at the dentist's chair, gives a low radiation dose and the 3D images give more information to the dentist than is obtained from current devices. This project will go further and develop software to analyse the 3D slices and _quantify_ the size of cavities. This will help dentists decide if a cavity needs to be filled or whether it can be safely left until next time and monitored to see if it will improve over time or get worse and need treating. This will make dentists more confident in their decisions and improve the quality of care that is provided. This is important as dental caries is one of the most prevalent diseases (42% of an adult population in the UK, Source: Murray et al. 2015, https://onlinelibrary.wiley.com/doi/full/10.1111/jcpe.12677).Enabling Adaptix to bring this healthcare technology to the UK, will support the NHS by reducing the cost of high-quality dental care, as well as enabling our dentists to make earlier and more accurate diagnoses.Adaptix is a UK company, setting up a UK manufacturing site, creating jobs in the UK. Supporting Adaptix will enable its UK technology to be brought to market, which will benefit the UK, as well as dental care worldwide."

“几乎每个人都会做牙科x光检查。这有助于牙医在诊断和治疗方面做出明智的决定。然而，每张x光片只是3D形状的2D阴影，因此评估诸如牙齿中的蛀牙等特征的大小和形状可能很困难。大型3D成像系统目前确实存在，但它们价格昂贵，只能在专业中心使用，而且辐射剂量相对较高。Adaptix提供了一种获取三维x射线数据的新方法。Adaptix已经将x射线发射器小型化，这意味着许多发射器可以排列在平板阵列中。从45个不同的位置发射电子x射线意味着可以获得3D信息，就像在不同位置有两只眼睛给我们深度感知一样。Adaptix的设备足够小，可以在牙医的椅子上使用，辐射剂量低，3D图像比目前的设备能给牙医提供更多的信息。这个项目将进一步开发软件来分析三维切片和量化空腔的大小。这将帮助牙医决定是否需要填充蛀牙，或者是否可以安全地保留到下一次，并监测它是否会随着时间的推移而改善或恶化并需要治疗。这将使牙医对他们的决定更有信心，并提高所提供的护理质量。这一点很重要，因为龋齿是最普遍的疾病之一（英国42%的成年人，来源：Murray et al. 2015, https://onlinelibrary.wiley.com/doi/full/10.1111/jcpe.12677）.Enabling Adaptix将这种医疗保健技术引入英国，将通过降低高质量牙科护理的成本来支持NHS，并使我们的牙医能够做出更早，更准确的诊断。Adaptix是一家英国公司，在英国建立了生产基地，在英国创造了就业机会。支持Adaptix将使其在英国的技术推向市场，这将使英国乃至全球的牙科保健受益。”
