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.
