Treatment times for cancer patients undergoing radiotherapy have been reduced by up to a fifth as a result of revolutionary beam-shaping technology.
Medical physicists in Leeds, England have developed a new device that continually reshapes the radiation beam to match the outline of the tumour as the beam rotates around the patient.
The beam is so finely targeted that less damage is done to healthy tissue surrounding cancerous cells, which means higher doses of radiation can be given, reducing treatment times by weeks.
Dr Elizabeth Healey travels to Leeds to see 86-year old lung cancer patient Allan Garnett receiving the pioneering treatment.
