X-ray imaging methods have been under development for over 100 years since the discovery of x rays by Röntgen in 1895, and the complete dependency of modern medicine on x-ray-based diagnostic radiography continues to motivate research to improve costs, efficacy, safety and the potential for screening and early diagnoses. However, there are known risks associated with exposure to radiation and it has been estimated that 1 in 200 of all cancer deaths can be attributed to diagnostic x-ray imaging. This critical need to produce better images with less radiation is the driving motivation for this proposal.

自1895年Röntgen发现x射线以来，x射线成像方法已经发展了100多年，现代医学完全依赖于基于x射线的诊断放射学，这继续激励着研究，以提高成本、疗效、安全性以及筛查和早期诊断的潜力。然而，已知有与辐射照射有关的风险，据估计，每200例癌症死亡中就有1例可归因于诊断性x射线成像。这种以更少的辐射产生更好的图像的关键需求是该提案的驱动动机。
