6. Linear accelerators, commonly known as linacs, are machines used
in various fields, including medical treatment (radiation therapy),
research, and industrial applications. Here are some examples of
linac machines:
1. Varian- TrueBeam , UNIQUE, CLINAC IX, TB STX, VITAL BEAM ,
Truebeam edge ,ethos ,halcyon
2. Elekta- Synergy ,Synergy platform ,harmony ,Hpro, unity, compact
,Elekta varsaHD
3. Siemens Oncor Impression
4.Accuray CyberKnife ,Tomotherapy
5.Toshiba Primus
6.Mitsubishi ML-10
7.Philips SL25
Many more…..

7. DIFFERENCE BETWEEN COBALT 60 & LINACS
• Radioactive source
• Gamma rays
• Specific energy level
(1.17 and 1.33 MeV)
• Longer treatment times
• Shielded room
• Less maintenance
• Limited half-life,(5.26
years)
• Lower dose rate
• No Radioactive source
• Xrays
• Produce X-rays of
varying energy levels
• Shorter treatment times
• No need of too much
shield
• More maintenance
• No such half life
• High Dose Rate

8. What Is Game changer
• Its MLCS IN LINAC (linear accelerator )

9. • The Multi-Leaf Collimator is a device used in radiation therapy to
shape the radiationbeam to conform to the shape of the tumor.
• It consists of a series of movable leaves or vanes that can be
adjusted to create a custom-shaped aperture for the radiation
beam.
• This helps in deliveringa more precise dose to the tumor while
minimizingexposure to surroundinghealthy tissues.
• made up of a series of individualleaves, which are often composed
of a high-density material such as tungsten. Tungsten is commonly
used in medical radiation therapy because of its ability to effectively
block and attenuate X-rays.
