Smartphone cameras are advancing rapidly every year. While smarter smartphone photography can now produce stunning, eye-appealing photos, it can also be applied to clinical applications. In this Tech Talk, Professor Terence Leung will share their team’s experiences in using smartphones to (a) screen newborn babies for significant jaundice in Ghana and the UK, (b) screen pregnant women in India and young children in Ghana for anaemia, and (c) monitoring the deterioration (decompensation) of cirrhosis patients. Technical issues such as the effects of ambient lighting, differences in the spectral sensitives of colour sensors in different smartphones, and other environmental effects will also be discussed. The talk will end with a discussion on the future trend in smartphone imaging and its impacts on medical imaging.
Professor Terence Leung is Professor of Digital Health in the Department of Medical Physics and Biomedical Engineering at University College London (UCL) in the UK. Funded by the NIHR, USAID, EPSRC, BHF and industrial partners, his research activities encompass diffuse optics, acousto-optics, cerebral/muscle oxygenation monitoring, medical imaging, motion capture, healthcare app development and AI during his 25 years at UCL. He works closely with clinicians from UCL’s 8 affiliated hospitals in the areas of neonatology, neurology, rhinology and ophthalmology.
Clean water and clean air are vital for public health. This project focuses on developing high-efficiency and environmentally sustainable filters for removing harmful air/water pollutants. The team has developed novel architectures and functionalities for the filters to achieve high permeance, high removal efficiency, and excellent reusability.
