About the Project

Applications are invited for a research studentship in the field of Magnetic Resonance Imaging system engineering leading to the award of a PhD degree.

Recent research in the Department has resulted in the development of a novel Magnetic Resonance Imaging (MRI) system designed to exploit field-related anisotropies of collagen. Conventional MRI cannot accurately diagnose tissues such as ligaments, tendons and cartilage because the received signal is too weak and those tissues appear very dark. However the signal intensity can be significantly increased changing the orientation of the main field to the subject, and is maximized if the angle is 55 degrees (the “Magic Angle” effect). The prototype MRI employs a magnet that can be rotated about 2 axes and it is particularly well suited for the imaging of limbs. Also, by using image processing techniques to analyse the signal variation with the field angle, it is possible to obtain important new information about tissue microstructures. The aim of the current project is to carry out the necessary technical work related to MRI system and image processing and to conduct early stage clinical trials.

This PhD project will focus on the MRI aspects related to maximizing the image quality. This will primarily involve radio frequency (RF) front end design using multiple antenna arrays, methods for automatic tuning in-situ, calibration, and integration with the MRI system. The work will involve a significant amount of electronics development and testing, and it will demand a high level of practical skill.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 1st class or 2:1 honours degree in Physics or Engineering, and an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits. Experience and understanding of RF electronics and circuits is essential. Good team-working, observational and communication skills are essential.
