linear accelerator

GC: n

CT: A linear accelerator (LINAC) is the device most commonly used for external beam radiation treatments for patients with cancer.
The linear accelerator can be/is used to treat all parts/organs of the body. It delivers high-energy x-rays to the region of the patient's tumor. These x-ray treatments can be designed in such a way that they destroy the cancer cells while sparing the surrounding normal tissue.

N: 1. - linear (adj): from French linéaire, from Latin linearis ‘belonging to a line’, from linea ‘string’, ‘line’.
- accelerator (n): from Latin accelerator, agent noun from accelerare ‘to hasten’, ‘make haste’.
  • Abbreviation: linac.
2. A device in which charged particles are accelerated in a straight line by successive impulses from a series of electric fields
3. Linear accelerator is often shortened to ‘linac’.
4. Proton linacs:
  • typically operate at frequencies of about 200 megahertz (MHz),
  • electric fields are set up as standing waves within a cylindrical metal ‘resonant cavity’, with drift tubes suspended along the central axis.
Electron linacs:
  • the accelerating force is provided by an electromagnetic field with a microwave frequency of about 3,000 MHz,
  • utilize traveling waves rather than standing waves,
  • because of their small mass, electrons travel at close to the speed of light at energies as low as 5 megaelectron volts.
5. In medicine, a linear accelerator (LINAC) is the device most commonly used for external beam radiation treatments for patients with cancer. The linear accelerator is used to treat all parts/organs of the body. It delivers high-energy x-rays or electrons to the region of the patient's tumor. These treatments can be designed in such a way that they destroy the cancer cells while sparing the surrounding normal tissue. The LINAC is used to treat all body sites, using conventional techniques:
  • Intensity-Modulated Radiation Therapy (IMRT),
  • Volumetric Modulated Arc Therapy (VMAT),
  • Image Guided Radiation Therapy (IGRT),
  • Stereotactic Radiosurgery (SRS),
  • Stereotactic Body Radio Therapy (SBRT).
