Metal aids cancer treatment

A RADICAL new approach to controlling radiotherapy in the treatment of cancer patients could be ready for clinical use within two years.

Researchers at Coventry University's multi-disciplinary control theory and applications centre have adapted a technique that is used in industry to help controlthe accuracy and intensity of radiation beams.

The beams are passed through a block of metal alloy, moulded to an individual patient's requirements. The alloy "compensator" improves the accuracy of the radiation beam, reducing the damage to healthy tissue. It will also intensify the dosage, making the treatment more effective.

The technique has been tested clinically, and the university is looking for Pounds 100,000 backing.
