A photography exhibition has been set up inside Oxford's Covered Market which showcases some of the pioneering research undertaken by the NHS.
The Body Unlocked: How Research is Changing Lives has life-sized photographs of the people involved in the studies, as well as microscopic images of cells and bacteria.
In 2018/19 there were 1,930 studies involving 39,129 participants at Oxford University Hospitals NHS Foundation Trust.
Director of research and development Professor Keith Channon said he hoped the exhibition would showcase the "ground-breaking research", highlight the "contributions of patients and members of the public" and encourage people to "get involved in research studies that can lead to new and improved treatments in the NHS".
The exhibition will run until 15 April, and then travel around the Thames Valley at museums, libraries and town halls.
