Ultra-high-field Magnetic Resonance Imaging (MRI) systems offer the potential for faster, more accurate diagnostic imaging. However, current applications are limited by the fundamental challenge of strong interactions between the electromagnetic field and human tissues, which result in poor image quality and/or compromised patient safety. Using a novel, subject-specific imaging approach, this research will design and develop an ultra-high-field radiofrequency technology capable of offering high-performance imaging without jeopardising patient safety. This research will lay the groundwork for the translation of ultra-high field MRI research into clinical practice, generating new capabilities for diagnostic technologies.

超高场磁共振成像（MRI）系统提供了更快、更准确的诊断成像的潜力。然而，当前的应用受到电磁场与人体组织之间强相互作用的根本挑战的限制，这导致图像质量差和/或患者安全受损。使用一种新的，特定于受试者的成像方法，该研究将设计和开发一种超高场射频技术，能够提供高性能的成像，而不会危及患者的安全。这项研究将为超高场MRI研究转化为临床实践奠定基础，为诊断技术创造新的能力。
