The medical imaging technique of positron emission tomography (PET) has been adapted for these studies, and a new technique of positron emission particle tracking (PEPT) has been developed, by which a single labelled particle can be accurately tracked at high speed inside operating equipment.Ê

Radioactive tracers are produced using our in-house cyclotron, and a continuous programme of research and development is devoted to extending the range of isotopes and forms available. Currently tracer particles down to 200µm in size are produced by ion exchange techniques. The tracers are detected using a positron camera comprising a pair of position-sensitive gamma ray detectors.Ê

A new positron camera has recently been installed, giving a factor of 20-improvement in sensitivity and count rate, which provides opportunities for further extensions to the imaging and tracking techniques. There are also plans to develop a simplified transportable PEPT system.Ê
