In this short video, Heather Williams from the Christie Hospital explains the principles of how gamma cameras are used within oncology. Williams, a senior medical physicist for nuclear medicine describes how the equipment is used for functional imaging, by tracking radioactive tracers injected into patients. Such gamma cameras are typically used  as part of cancer diagnosis and for the monitoring of treatment.

This video was part of a series of films recorded at the Christie NHS Foundation Trust in Manchester, UK. They included a look inside the centre’s proton-therapy system, its brachytherapy options and MRI equipment.
