Existing clinical UCT systems are custom-built at high cost and with a long lead time, which can be prohibitive for some research groups. At UCL we are developing FlexUCT: a design framework for a benchtop UCT system that will allow novel data acquisition protocols and reconstruction algorithms to be tested immediately on a physical system, accelerating progress towards fast and accurate...

Breast cancer is a common cancer and a major health concern affecting the lives of many women worldwide. According to the World Health Organization (WHO) breast cancer has an estimated annual incidence rate of 2.1 million and is responsible for about 15% of all cancer related deaths around the world. We have previously introduced a novel photoacoustic tomography (PAT) system for breast cancer...

Full-waveform inversion (FWI) is an iterative image-reconstruction technique used in exploration seismology to produce high-quality tomographic images for acoustic properties of the subsurface by minimising the misfit between acquired and modelled data. FWI has also been shown to have some exciting applications in ultrasound imaging of soft tissue, including breast cancer diagnosis, however...
