One of the main benefits of radiotherapy with protons and heavy ions is the physical dose distribution characterised by the Bragg Peak and the ensuing sharp dose fall-off. However, these strong dose gradients also entail the need for an irradiation accuracy of approx. 1–2 mm. Real uncertainties[for full text, please go to the a.m. URL]
