Ten years ago AEI installed, at the Hammersmith Hospital, the first linear accelerator in the world
to be used for X-ray therapy. It is still in constant use. Since 1953 linear accelerators have become a
feature of advanced megavoltage therapy departments throughout the world and AEI has
supplied more than any other manufacturer.
Taking advantage of the most recent advances in accelerator technology and retaining the essential
isocentric geometry of the earlier machines, AEI has now produced a much more compact equipment -
the Series III - which permits unhindered rotation of the X-ray head about the patient through more
than 360°. Beam energies are preset at the factory to 5 or 6 MeV as required
Two Series III machines have already been ordered; one for the Queensland Radium Institute,
Brisbane, Australia and the other for the Sahlgrenska Hospital, Sweden.

When you specify a Guardian 150 X-ray tube, you ensure that full
advantage is obtained from your high powered equipment. Typical
short, high current exposure ratings of this tube allow chest ex-
posures to be made in as little as 0.003 seconds.
Furthermore, the exceptiona//y good thermal capacity of the Guardian
150 has given it a proved performance when used for angiographic
series and cine radiography.
These important features are worth considering when ordering new

Vickers 6 MeV supervoltage
X-ray therapy set
gives optimum supervoltage therapy
as routine treatment
The Vickers unit is proving its worth in leading hospitals; its overall simplicity of design, ease of operation and reliability set
new standards for the wider use of linear accelerators.
It is the only machine which combines all these features:
Value-Design simplification, adoption of recent technical advances and the elimination of unnecessary facilities have produced
the lowest cost linear accelerator available.
Simplicity of Operation - To facilitate rapid and accurate set-up by a single operator, all controls for this function are
conveniently grouped on the X-ray head, thus enabling the maximum number of patients to be treated with the minimum
Reduced Maintenance - T h e degree of maintenance required has been greatly reduced by the development of a sealed-off
tube which dispenses with the need for vacuum equipment, by the replacement of thermionic valves with solid state amplifiers,
and by robust construction in an all steel welded gantry.
Ease of Installation - Installation is a relatively simple operation and building requirements are not
extensive, since all the major equipment is accommodated within the gantry. No separate apparatus
room is necessary, and the set is shipped and installed as an integral unit.
Complementary to the advanced technical features of the set itself every consideration has been
given to likely developments in its use. The Vickers unit is the only design which enables a high
pressure oxygen chamber to be incorporated in place of the couch.
