The medical linear accelerator (linac) is the primary workhorse for radiation oncology. While the underlying principle of a linac is remarkably simple, implementation of that principle to produce a consistent stable beam requires a precise and sophisticated design.

A linear particle accelerator (often shortened to linac) is a type of particle accelerator that accelerates charged subatomic particles or ions to a high speed by subjecting them to a series of oscillating electric potentials along a linear beamline.

A LINAC is a device that generates high-energy x-rays and electrons in the range of mega voltage energy, or MV, for cancer treatment. The high-energy x-ray beams penetrate deep into the body and spare more superficial tissues, whereas electron beams are more beneficial for superficial lesions and can spare deeper normal structures.

A medical linear accelerator (LINAC) customizes high energy x-rays or electrons to conform to a tumor's shape and destroy cancer cells while sparing surrounding normal tissue. It features several built-in safety measures to ensure that it will deliver the dose as prescribed and is routinely checked by a medical physicist to ensure it is working ...

This chart compares Varian linear accelerator models across multiple generations, providing key specifications and features to assist healthcare professionals in making informed decisions about radiation therapy equipment.

UVA has four different linear accelerators that offer conventional radiation, IMRT, VMAT, IGRT, SRS, SBRT, and other treatment modalities. We also have an MRI linac for difficult to treat tumors that require daily adaptive planning. UVA offers respiratory gating utilizing a …

A medical linear accelerator, or linac, is a particular type of machine that produces high-energy x-ray or electron beams for use in radiation therapy. This method of treatment is commonly referred to as “external-beam radiation therapy” because the radiation beams are generated at a distance outside the patient’s body.

Linear accelerator (linac) – a device that accelerates charged particles in a straight line. Linac types: • Electrostatic – electric field is produced by a fixed voltage (e.g., old TV tubes) • Induction – electric field is produced by changing magnetic flux • Radio-Frequency (RF) – fields are produced by external sources of RF power

2020年5月28日 · In this chapter the various types, near term uses, and future directions of linacs are discussed. There are many standard types of linac structures, several are shown in Figs. 7.1 and in Figs. 7.6 and 7.7 in Sect. 7.4. A complete linac system includes an RF power source, the microwave power waveguide distribution, the accelerating structure ...

beams of electrons, positrons, protons, antiprotons, and heavy ions. Linac parameter possibilities include pulsed versus continuous wave, low and high beam powers, low and high repetition …
