This research project aims to advance engineering knowledge by applying an innovative, fibre-optics-based discrete optical coherence tomography to technology used for atrial fibrillation catheter ablation. RadioFrequency catheter-based ablation is far superior to cardiac drug therapy for atrial fibrillation patients. RadioFrequency catheters are not equipped with real-time lesion formation monitoring means, which enable the assessment of continuity-transmurality and prevent extra-cardiac complications, such as steam pops. Optical Coherece Tomography enables non-invasive, microscopic lesion formation assessment in real time during atrial fibrillation ablation procedures. The expected outcomes of this project are to develop a new hybrid fibre-optic/RadioFrequency catheter system and user-friendly driving software that will enable cardiac electrophysiologists to perform three key tasks not previously available.Read moreRead less

This project expects to develop new techniques and devices for biomedical imaging. Biomedical imaging is widely used for medical diagnosis and treatment, with different types of imaging providing different information. This project aims to develop techniques that will allow imaging using safer nonionising terahertz radiation, with better resolution than ever before. It plans to combine this with optical, visible and infrared imaging to give very broad spectral information. It also aims to develop probes for direct interfacing to tissue to collect and deliver electrical signals, light and fluids, and to image neural activity. The intended outcome of the project is to allow single cancer cells within tissue to be identified to allow early stage cancer detection, and to develop implantable devices for neuroscience research and pain management.Read moreRead less
Ultra-fast serialised all optical image processing: addressing the electronic bottleneck in the world's fastest camera. Serial time encoded amplified microscopy can capture over a million frames per second. At this rate, a megapixel image would fill a terabyte hard disk in a second. We will use photonics to condense and manipulated the video stream so that only the important features are 'seen', making it practical to process and store on a computer.
Smart surfaces for monitoring cellular activity in real time: from multiple to single cells. Cells are the fundamental building block of life. In the proposed research smart surfaces will be developed that can monitor the release of enzymes from single cells and from multiple cells. This work will be important for developing cell chips for drug discovery, toxin detection and biomedical research and devices to monitor infection.

Summary
Miniaturised fibre-optic probes for biomedical image and sensor data fusion. The project aims to develop new types of tiny biomedical imaging devices based on optical fibres that can be inserted into the body via hypodermic needles or catheters. These devices will have the ability to generate a three-dimensional image of the tissue region. As the devices will also be able to sense biochemical or mechanical properties of the tissue, they can be used to differentiate healthy from diseased tissue. ....Miniaturised fibre-optic probes for biomedical image and sensor data fusion.

As the devices will also be able to sense biochemical or mechanical properties of the tissue, they can be used to differentiate healthy from diseased tissue. These minimally invasive devices will produce information-rich multidimensional fused image and sensor data, opening up new possibilities for biologists and medical researchers to study disease progression and treatment in living animals and humans, with great potential for scientific discovery.Read moreRead less
