How the Linear Accelerator is Transforming Radiation Therapy

December 14, 2023 | Radiation Oncology

Learn about the benefits of Linear Accelerator treatment and why this may be the most effective option for your cancer journey.

The medical linear accelerator (also known as LINAC) has become one of the most efficient radiation therapy tools for targeting and eliminating cancerous tumors. Revere Health’s Radiation Oncology team uses a TrueBeam linear accelerator to help patients accelerate their treatment process with more effective results.

What is a linear accelerator?

A LINAC uses targeted X-rays or electron beams to destroy cancer cells while preserving the surrounding healthy tissue and thus reducing related side effects. LINACs are used to treat virtually all cancer types and have become a cornerstone of radiation therapy thanks to their precision, versatility, efficiency, and ability to deliver “tattoo-less” treatment.

One of the primary advantages of the LINAC is its ability to deliver highly precise and focused radiation beams to cancerous tissues. Unlike traditional treatment methods, the LINAC allows clinicians to tailor the radiation dose with remarkable accuracy, minimizing damage to surrounding healthy tissues. This precision is crucial for targeting tumors in challenging anatomical locations, improving the efficacy of the treatment while reducing the risk of side effects.


The LINAC provides oncologists with the flexibility to customize therapies based on individual patient needs. Intensity-Modulated Radiation Therapy (IMRT), Image-Guided Radiation Therapy (IGRT), and Stereotactic Body Radiation Therapy (SBRT) are just a few examples of the advanced techniques that can be seamlessly integrated into LINAC systems. This versatility ensures that patients receive the most appropriate and effective treatment for their specific cancer type and stage. Newer LINAC models use advanced imaging technology to accurately target tumors and adjust energy beams to the tumor’s shape and size. The LINAC also supports real-time imaging, such as cone-beam computed tomography (CBCT), enabling clinicians to visualize the tumor and surrounding structures with exceptional clarity just before each treatment session.


The LINAC gives patients the safe, high-precision treatment they need, usually in only 15-30 minutes per session. With advanced technologies like RapidArc and volumetric modulated arc therapy (VMAT), LINAC systems can optimize treatment delivery, significantly reducing the time patients spend in the treatment room and improving comfort.

Tattoo-Less Treatments

Combining our LINAC with the AlignRT image guidance system can allow for mark-free treatments. Some radiation therapy treatments require radiographers to make a few permanent “tattoos” on the skin so they know where to accurately administer the treatment. The LINACs CBCT capabilities along with the AlignRT system allow us to use imaging mapping to target the cancerous growth, so marking the skin with a permanent tattoo is not required.

Revere Health Radiation Oncology develops personalized treatment plans to fast-track the process of diagnosis to treatment. Our radiology team is proud to offer the latest and most innovative technology to provide healing and a better quality of life to our cancer patients.
