Quantification of dental caries using a 3D X-ray device at the dentist's chair

“几乎每个人都做过牙科X光检查。这些帮助牙医做出关于诊断和治疗的明智决定。然而，每个X射线只是3D形状的2D阴影，因此评估牙齿中的空洞等特征的大小和形状可能很困难。大型3D成像系统今天确实存在，但它们价格昂贵，只能在专科中心使用，并且它们的辐射剂量相对较高。Adaptix有一种获得3D X射线数据的新方法。Adaptix已经将X射线发射器进行了扩展，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X射线意味着可以获得3D信息，就像在不同的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图像可以为牙医提供比现有设备更多的信息。该项目将进一步开发软件来分析3D切片并量化空腔的大小。这将有助于牙医决定是否需要填补一个洞，或者是否可以安全地留到下次，并监测它是否会随着时间的推移而改善或变得更糟，需要治疗。这将使牙医对自己的决定更有信心，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（英国成年人口的42%，来源：Murray et al. 2015，https：//onlinelibrary.wiley.com/doi/full/10.1111/jcpe.12677）。使Adaptix能够将这项医疗保健技术带到英国，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更早更准确地诊断。Adaptix是一家英国公司，在英国建立了一个制造基地，在英国创造就业机会。支持Adaptix将使其英国技术能够推向市场，这将有利于英国以及全球的牙科护理。"

"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."
