PARTS OF LINEAR ACCELERATOR Flashcards
- Directs the electron beam to the target or scattering foil
Bending Magnet
- it is where the electrons interact to produce x-rays

Scattering Foil -
. Ion Chamber
Electron gun -
Magnetron
Beam Flattening Filter
Collimators
- placed along the path of the x-ray
beam in order to attain homogenous intensity of the X-ray beam in the entire field.
Beam Flattening Filter
placed along the path of the electron beam to scattered the pencil thin electron beam.
Scattering Foil -
- a vacuum tube where the electrons are
accelerated.
Wave guide
- hollow tube with gas usually air where the
process of ionization occurs. It controls and switches off the equipment for an adequate radiation to be used.
Ion Chamber
- it produces electron to be accelerated
Electron gun
device that produces microwaves.It functions as a high power oscillation generating microwave pulses of several microsecond during and with a repetition rate of several hundred pulses per second.
Magnetron
- restrict the beam to desired beam size or field size
Collimators
The radiation therapy ___ is a diagnostic x-ray machine mounted on a rotating gantry which provides geometries identical with those found on megavoltage therapy machines. Simulators can be used in either a radiographic or fluoroscopic mode to provide diagnostic quality images on film or a television I monitor respectively
simulator
During ____, the patient is positioned on the table using appropriate treatment accessory devices and the table is raised and rotated under the gantry. The treatment area is determined based upon review of any related diagnostic studies, operative reports, CT
scan, X-ray, MRI or isotope studies, palpation of the site and tumor
visualization.
