A Bristol hospital is using a machine to treat brain tumours without the need for a knife.
The machine at the Bristol Oncology Centre uses gamma radiation to target tumours - without the risks of traditional surgery.
Up to 160 patients are expected to be treated with the new £2.5m machine over the next 12 months.
