Project Title: Novel BO and B1 shim enabled MRI transceive array coils for structural, functional and metabolic imaging at ultra‐high field
Group: Section for Magnetic Resonance
Supervisors: Esben Thade Petersen, Vitaliy Zhurbenko, Irena Zivkovic and Vincent Oltman Boer

Project Description: 

Magnetic resonance imaging (MRI) is the most versatile medical imaging platform, including non-invasive brain and spine imaging. Ultra-high field MRI allows increased image resolutions due to the higher spin polarization and an accompanied increase in Larmor frequency of the protons. However, the resulting shorter wavelength poses a challenge at ultra-high field MRI. The coverage and homogeneity of the RF field needed for imaging become increasingly harder to achieve while at the same time operating within safe limits. 
The project aims to investigate how to resolve and control RF field interactions to unleash the full potential of ultra-high field MRI with fast subject-tailored RF safety. There will be designed a multi-channel head and spine transmit/receive coil based on a novel shielded coaxial cable coil approach, and software developments based on analytical and/or deep learning algorithms will be designed to ensure optimal B0 and B1 field distributions in the individual patient while operating within safety limits. 

Perspective:

In the future, this will allow for the fast development of advanced coils for the Ultra‐high field MRI, something that currently is very time-consuming. The outcome, a novel B0 and B1 shim enabled MRI transceive array coils for structural, functional, and metabolic imaging at the ultra‐high field, will benefit the entire international MRI research community. Currently, the availability of multi‐transmit coils for UHF MRI is rather limited, and real‐time safety procedures that can handle the coils’ safety are lacking. Therefore, the current use of these coils uses very conservative power levels, which defeats the purpose of ultra-high field MRI. Finally, the project will put DTU and Denmark in the absolute elite within advanced coil development for MRI, and many shared publications are expected between the involved partners at Danish Research Centre for Magnetic Resonance and the Technical University of Eindhoven, the Netherlands.
