This project aims to augment the capabilities of Magnetic Resonance Imaging (MRI) systems, using continuous wave (CW) transmission and signal reception, to image objects using very low excitation power. Any given MRI sequence tries to solve an inverse problem, involving estimation of some subset of hidden states and parameters of the system, given the observed data. Using transient and steady-state CW magnetisation dynamics to solve inverse problems is expected to advance technology toward lower power, lower cost solutions for MRI scanners in healthcare and industrial applications, including materials science and mineral processing.

该项目旨在增强磁共振成像（MRI）系统的能力，使用连续波（CW）传输和信号接收，使用非常低的激励功率对物体进行成像。任何给定的MRI序列试图解决一个逆问题，涉及估计的一些子集的隐藏状态和参数的系统，给定的观测数据。使用瞬态和稳态CW磁化动力学来解决逆问题，有望推动医疗保健和工业应用（包括材料科学和矿物加工）中MRI扫描仪的低功耗、低成本解决方案的技术发展。
