Quantum Entanglement Tomography for enhanced medical imaging

量子纠缠层析成像（QET）是一种利用光子对的量子纠缠产生低噪声成像技术。当一个正电子与一个电子湮灭时，两个能量相等的光子向大约相反的方向发射。正电子发射断层扫描（PET）成像通过计数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，包括住院散射和随机巧合，使得难以将“真”光子对与其他过程引起的“假”光子对分开。QET利用来自正电子发射的光子对的量子纠缠，该项目将利用该技术创建一种医学成像技术，该技术将显示出比PET更高的图像质量。其他好处包括更少的剂量和更快的检查时间。该项目结合了爱丁堡大学和Kromek，前者已经证明了QET的可行性，后者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

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
