Healthcare need: Computed Tomography (CT) capability in many hospitals worldwide is under-constraint, resulting in delays to planned procedures. CT scans are expensive per scan, and the increasing use (typically>10% per year) is a factor in driving healthcare costs beyond inflation. There is a need for a lower-cost, lower-dose 3D imaging capability in healthcare. Significance: 3D imaging is a fundamental clinical tool as it enhances the sensitivity and specificity of diagnosis, and allows enhanced characterisation over time. Innovation: Low-dose 3D 'Digital Tomosynthesis' ('DT') imaging is currently achieved using a source on a computer controlled mover, or using a series of separate stationary tubes. Current DT solutions (used in Breast Imaging and General Radiology) are expensive (circa $450,000 fully installed) and so large the solution can only be fixed in place. The Adaptix Flat Panel Source facilitates a highly portable and low-cost tomosynthesis solution with enhanced resolution. Outcome: We see a way to allow to produce a 3D imaging solution, small (circa 20kg) and cheap enough (<$100,000) to be deployed on a mobile basis within hospitals and polyclinics. The innovative analysis by NPL will enable understanding of the variation in emitter tip performance and aid developments that enhance lifetme, reduce variation and reduce manufactutring costs.

医疗需求：全球许多医院的计算机断层扫描（CT）能力不足，导致计划程序延迟。CT扫描每次扫描都很昂贵，并且越来越多的使用（通常每年>10%）是推动医疗保健成本超过通货膨胀的一个因素。在医疗保健中需要更低成本、更低剂量的3D成像能力。重要性：3D成像是一种基本的临床工具，因为它提高了诊断的灵敏度和特异性，并允许随着时间的推移增强表征。创新：低剂量3D“数字断层合成”（“DT”）成像目前使用计算机控制的移动器上的源或使用一系列单独的固定管来实现。目前的DT解决方案（用于乳腺成像和普通放射学）价格昂贵（完全安装约450，000美元），而且解决方案非常大，只能固定在适当的位置。Adaptix平板源有助于实现高度便携和低成本的断层合成解决方案，并具有更高的分辨率。结果：我们看到了一种方法，可以生产一种3D成像解决方案，体积小（约20公斤），价格便宜（<10万美元），可以在医院和综合诊所内以移动的方式部署。NPL的创新分析将使人们能够了解发射器尖端性能的变化，并有助于提高寿命，减少变化和降低成本。
