  The use of a ccelerators for medical applications has evolved from initial
experimentation to turn-key devices commonly operating in hospitals. New
applications are continuously being developed around the world, and the
hadrontherapy facilities of the newest generation are placed at the frontier
between industrial production and advanced R&D. An introduction to the
different medical application accelerators is followed by a description of the
hadrontherapy facilities, with special emphasis on CNAO, and the report closes
with a brief outlook on the future of this field.
