title: A multi-purpose contour projector for use in radiotherapy treatment planning.
abstract: The multi-purpose contour projector is a compact piece of apparatus of simple design made entirely in the physics workshop and mould room. Its introduction to the planning department has standardised and simplified the localisation technique so as to make the system more accurate. The device is now used routinely on all head and neck moulds.
