Cancer centre's first for quality
The cancer centre at the Norfolk and Norwich University Hospital has become one of the first clinics in the world to use a new quality assurance system used in the hi-tech radiation treatment of cancer patients.
Four patients have now benefited from a unique ‘all-in-one’ quality assurance system known as portal dosimetry that double-checks the patient will get exactly the right dose of radiation in the right position as part of a treatment technique called intensity modulated radiotherapy treatment (IMRT). IMRT is only suitable for a small number of patients and is only available in a few
With IMRT, physicists and radiotherapists are able to shape the treatment beam to more precisely match the shape of the tumour, sparing a greater amount of surrounding tissue. This can be especially beneficial in head and neck cancers to protect the salivary glands from exposure to radiation. Using this approach, the dose can also be varied across the tumour, ensuring the more metabolically active parts of the tumour receive the most radiation.
