Abstract: The present invention therefore provides a method of treating the surface of an item for a radiotherapy apparatus, comprising the steps of machining into a planar reflective surface of the item a stepped profile, each step having a first surface angled to the planar reflective surface such that, in use, the first surface reflects light incident on the planar reflective surface away from the isocentre of the radiotherapy apparatus and a second surface angled with respect to the planar reflective surface and the first surface such that, in use, the second surface is shadowed from light incident on the planar reflective surface by the first surface, the steps having a depth which does not exceed 2.15% of the total depth of the item.
