Varian 600C/D Linear Accelerator

The Varian 600 C/D linear accelerator offers clinicians an
efficient way to treat cancer patients.
The 600C/D provides an enhanced dynamic wedge mode,
which includes dose rate control and
precision jaw collimator movement to
create wedge-shaped dose distributions.
This ensures additional safety and accuracy,
and saves time by eliminating the need for
room reentry to add or remove the wedge.

Features
Enhanced dynamic wedge mode
Extended collimator head rotation
Dual independent jaws
Carbon-fiber top panels
Movable carbon-fiber support rails
Radiation beam automatically turns off to
prevent excess radiation/dose
Performs arc therapy in either a clockwise or
counterclockwise direction
Accessory mount for mounting block trays
Posterior support side rail and centerline panels
Couch accessories include a universal accessory clamp,
arm support, and hand grips
Offers a high dose rate capability of 100-600 MU at 6MV and
80-400 MU at 4MV
Optional independent modes for collimator
