项目摘要

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.

医疗保健需求：全球许多医院的计算机断层扫描 (CT) 能力受到限制，导致计划的手术延误。 CT 扫描每次扫描都很昂贵，而且使用量的增加（通常每年>10%）是导致医疗保健成本超出通货膨胀的一个因素。医疗保健领域需要低成本、低剂量的 3D 成像能力。意义：3D 成像是一种基本的临床工具，因为它可以提高诊断的敏感性和特异性，并可以随着时间的推移增强特征描述。创新：低剂量 3D“数字断层合成”(“DT”) 成像目前是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的。目前的 DT 解决方案（用于乳腺成像和普通放射学）价格昂贵（完全安装大约需要 450,000 美元），而且解决方案太大，只能固定到位。 Adaptix 平板源有助于实现高度便携、低成本的断层合成解决方案，并具有增强的分辨率。结果：我们找到了一种方法来生产 3D 成像解决方案，该解决方案体积小（约 20 公斤）且足够便宜（<100,000 美元），可以在医院和综合诊所内移动部署。 NPL 的创新分析将有助于了解发射器尖端性能的变化，并有助于延长使用寿命、减少变化和降低制造成本的开发。
