The Photoacoustic Imaging Goup was founded in 2002 and forms a sub-group of the UCL Biomedical Optics Research Laboratory, BORL. It currently comprises 17 researchers, funded through a combination of UK research council grants and industrial sponsorship. Our activities are directed towards the development of a promising new method of non-invasive biomedical imaging based upon the use of laser-generated acoustic waves for visualising the internal structure and function of soft tissues. Potential applications include the clinical assessment of breast cancer, vascular disease and skin abnormalities. The technique also has important applications as a research tool in the basic life sciences for undertaking molecular and genomic imaging studies, for example studying tumour physiology. Our current research encompasses the full range of activities in photoacoustic methods: photoacoustic detection and excitation instrumentation, modelling of photoacoustic signals, image reconstruction algorithms, spectroscopic methods and the application of the technique in the clinical and life sciences.

In addition to biomedical photoacoustic imaging, a range of ultrasound field measurement and imaging tools based upon the use of Fabry Perot polymer film sensing interferometers is being developed. These include a miniature wideband fibre optic hydrophone for characterising medical and industrial ultrasound fields and high speed 2D arrays for field visualisation and imaging applications in medicine and industrial NDT.
