How does a linear accelerator machine work?

The ion source emits a stream of electrons, which are accelerated towards the first drift tube due to the negative potential of the electrons and the positive potential of the drift tube. When the electrons enter the first drift tube, the RF source shifts its polarity. As a result, the first drift tube becomes negatively charged, and the second drift tube becomes positively charged. The electrons exit the first drift tube due to inertia and are simultaneously repelled by it and attracted to the second drift tube, propelling them forward in the same direction.

As the electrons accelerate, their velocity increases, causing them to cover longer distances in the same time. This necessitates longer drift tubes as the electrons approach the target to account for their higher velocity. Achieving very high velocities requires longer and more numerous drift tubes, which, in turn, makes the linear accelerator (linac) significantly longer.

Types of radiation therapy and linear accelerator machines

There are various types of radiation therapy machines used in oncology to deliver precise and targeted treatment to cancerous tumours:

  • Gamma knife radiosurgery units: The Gamma Knife is a non-invasive stereotactic radiosurgery system that uses multiple beams of gamma radiation to target and treat tumours in the brain and other areas of the body with high precision.
  • Proton therapy systems: Proton therapy delivers highly targeted radiation using protons, which can precisely target tumours while minimising damage to surrounding healthy tissues.
  • Brachytherapy machine: Brachytherapy involves placing radioactive sources directly into or near the tumour site, allowing for localised radiation treatment while sparing healthy tissues.
  • CyberKnife radiosurgery systems: CyberKnife is a robotic radiosurgery system that delivers high-dose radiation to tumors, adjusting for patient movement in real-time during treatment.
  • Linear accelerators (LINACs): LINACs use high-energy X-rays or electrons to deliver external beam radiation therapy, allowing for precise targeting of tumours from various angles.
  • Image-guided radiation therapy (IGRT) linac: IGRT combines imaging techniques with LINACs to verify and adjust the patient's position before and during treatment, ensuring accurate radiation delivery.
  • Intensity-modulated radiation therapy (IMRT) linac: IMRT uses LINACs to deliver precise radiation doses that conform to the shape of the tumour, minimising radiation exposure to nearby healthy tissues.
  • Stereotactic radiosurgery (SRS) linac: SRS delivers high doses of radiation to small, well-defined tumors in a single session, often used for brain tumors and other localised lesions.
  • Volumetric-modulated arc therapy (VMAT) linac: VMAT is an advanced form of IMRT that uses LINACs to deliver radiation continuously while the machine rotates around the patient, allowing for faster treatment times and precise dose delivery.

Each of these radiation therapy machines offers unique advantages and is used based on the type, location, and stage of the cancer, as well as individual patient factors and treatment goals.
