The aim of this project is to design and construct a multifunctional ultra-low magnetic field (ULF) magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) instrument equipped with novel magnetic field sensors. This project is significant because it will deliver an instrument with enhanced sensitivity which is capable of obtaining non-invasive three-dimensional structural imaging of samples. This instrument will enable operation of highly sensitive ULF-MRI or ULF-NMR with regenerative energy sources and be a low-cost solution; reducing operation and maintenance costs as well as power consumption.Read moreRead less
Rotating Radiofrequency Phased-array for 7 Tesla Magnetic Resonance Imaging. This project aims to develop a new type of radiofrequency coil array to ensure high-field magnetic resonance imaging (MRI), with all its benefits, is available for a broader range of applications. High-field MRI offers faster scans with more detailed images than lower field systems. This enhanced sensitivity potentially enables smaller structures to be resolved in the body. At high fields, however, standard radiofrequen ....Rotating Radiofrequency Phased-array for 7 Tesla Magnetic Resonance Imaging. This project aims to develop a new type of radiofrequency coil array to ensure high-field magnetic resonance imaging (MRI), with all its benefits, is available for a broader range of applications. High-field MRI offers faster scans with more detailed images than lower field systems. This enhanced sensitivity potentially enables smaller structures to be resolved in the body. At high fields, however, standard radiofrequency coils, an essential component of MRI systems, can distort images and induce potentially harmful tissue heating. The aim is to design and develop a rotating multi-channel radiofrequency coil array, with dedicated image reconstruction software, to overcome these limitations. This would facilitate detailed images that can be obtained quickly and safely.Read moreRead less

This project aims to investigate a new method for visualization of the quickest responses in human cone photoreceptors and nerve cells after a visible stimulus. Expected outcomes of this project include a better understanding of the origins of responses to a stimulus and how cells in the retina communicate. The scientific results will be helpful in a better understanding of the development of vision in the infant eye, to study peripheral vision in elite athletes and to quantify performance of virtual reality equipment for the military.

A Multi-Optrode Array for Closed-Loop Bionics. We will design, implement and characterise a disruptive multi-channel optrode array (MOA) to record and stimulate excitable living tissue. The MOA will be a combination of individual optical electrodes (optrodes) that either comprise a new class of liquid crystals, used to passively sense extracellular biopotentials, or microphotovoltaic cells that will be used for electrical stimulation of excitable tissue.

The MOA will be a combination of individual optical electrodes (optrodes) that either comprise a new class of liquid crystals, used to passively sense extracellular biopotentials, or microphotovoltaic cells that will be used for electrical stimulation of excitable tissue. By employing light for communication with optrodes, this new approach alleviates many of the wiring, packaging and encapsulation issues associated with existing devices. Computational modelling and in vitro testing in cardiac tissue and retinal neurons will demonstrate the utility of the MOA to sense and control electrical activity.Read moreRead less
Design of an optrode for next generation brain-machine interfaces. The project plans to use a new class of liquid crystals – deformed helix ferroelectric (DHF) liquid crystal – to sense extracellular biopotentials. In response to an applied electrical field, it has been shown that DHF crystals can modulate a polarised light source with extraordinary sensitivity and linear response down to the microvolt range.

The project plans to use a new class of liquid crystals – deformed helix ferroelectric (DHF) liquid crystal – to sense extracellular biopotentials. In response to an applied electrical field, it has been shown that DHF crystals can modulate a polarised light source with extraordinary sensitivity and linear response down to the microvolt range. Using this technology, the project plans to initially design and test a single optrode device on the bench, before in vitro testing and characterisation using two-photon microscopy. The final design would be a higher density sensor array using a fibre optic source and multiple optical couplers. This may support the development of new ways to implant sensing and diagnostic devices in the body.Read moreRead less

This project aims to address low signal-to-noise ratio in ultra-low-field (ULF) MRI, using dynamic, mechanically-operated small permanent magnet arrays to generate magnetic fields needed for pre-polarisation and spatial encoding. Superconducting magnets make conventional MRI scanners too heavy and expensive for much of the world’s population. ULF MRI instruments offer image contrast mechanisms, are less costly and potentially portable, so can be used in unconventional situations. This project will design, construct and evaluate an instrument capable of three-dimensional 3D ULF-MRI. This technology is expected to be useable in field hospitals and emergency settings, and to benefit fields including magnetic refrigeration and remote sensing.Read moreRead less

This project aims to develop technologies for imaging through a multimode fibre that controls and measures each property of light; amplitude, phase, polarisation, wavelength and space as it propagates through an optical fibre. This will be pursued through the development of three prototype systems, where each system targets a particular property of light. The outcomes would ultimately enable multimode fibres to act as ultracompact, general-purpose optical conduits into the body through which a wide array of biomedical techniques can be performed in a minimally invasive fashion not currently possible. This project will provide significant benefit to the study of fundamental phenomena in optical fibres.Read moreRead less
