New gamma ray camera ‘can improve cancer diagnosis’

A mini gamma ray camera is being developed by researchers in the UK that could make cancer treatment much easier and more convenient.

Scientists at the Universities of Leicester and Nottingham have created a hybrid mini camera that combines optical and gamma imaging in a handheld unit, allowing it to potentially be used at patients' bedsides.

Whereas traditional gamma cameras are housed in specialised rooms within nuclear medicine departments, this portable device allows for the diagnosis and removal of tumours and lymph nodes across a variety of clinical settings.

It can also be used for small organ imaging, surgical investigation and visualisation of drug delivery.

Dr John Lees from the University of Leicester's department of physics and astronomy said: "Our system will improve surgical cancer treatments, reducing mortality and morbidity by enabling surgeons to increase lymph or tumour removal efficiency while minimising damage to normal tissue."

The universities have developed a spin-out company, Gamma Technologies, which will take charge of the future commercialisation of the device.
