This proposal presents Quantum Entanglement Tomography (QET) as a technique which utilises the quantum entanglement of photon pairs to create a low noise imaging technology. When a positron annihilates with an electron, two photons of equal energy are emitted in approximately opposite directions. Positron Emission Tomography (PET) imaging determines the position of a positron-containing radiotracer by counting numerous photon pairs, but the imaging is hindered by physical processes, including in-patient scattering and random coincidences, making it difficult to separate “true” photon pairs from “false” pairs caused by other processes. QET utilises the quantum entanglement of the photon pairs from the positron emission, and this project will use the technique to create a medical imaging technology which will show improved image quality over PET. Other benefits include lower doses and faster examination times. The project combines the University of Edinburgh, who have proven the feasibility of QET, with Kromek, a leading developer and supplier of radiation detector technology. The project will see the development of a prototype detection system, alongside the reconstruction algorithms required for commercialisation

该提议将量子纠缠层析成像(QET)作为一种利用光子对的量子纠缠来创建低噪声成像技术的技术。当一个正电子与一个电子湮灭时，两个能量相等的光子以大致相反的方向发射。正电子发射断层扫描(PET)成像通过计数大量的光子对来确定含有正电子的放射性示踪剂的位置，但成像受到物理过程的阻碍，包括住院患者的散射和随机巧合，这使得很难区分由其他过程引起的“真”光子对和“假”光子对。QET利用正电子发射中光子对的量子纠缠，该项目将使用这项技术来创建一种医学成像技术，该技术将显示出比PET更好的图像质量。其他好处包括更低的剂量和更快的检查时间。该项目结合了爱丁堡大学，他们已经证明了QET的可行性，Kromek是辐射探测器技术的领先开发商和供应商。该项目将开发一个原型检测系统，以及商业化所需的重建算法
