Elekta Unity

Elekta Unity See the difference.

Unity allows you to see what you could never see before.

Elekta Unity is our ground-breaking MR-Linac. It brings together diagnostic quality MR imaging with a linear accelerator to deliver unprecedented visibility and precision. The system’s continuous, rich and timely insights into motion and response enable truly precise and personalized radiotherapy.

Dynamic real-time adaptation

Provides the ability to tailor treatment based on changes in the shape, size and position of the tumor and surrounding anatomy.

“So this is what I really call opening your eyes. No MRI (scan) for three months to an MRI every single day.”
Dr Arjun Sahgal


Visualize daily changes with sub-millimetric resolution in 5 different ways


Instantaneously react to changes in the tumor and reshape the dose in 12 clicks


See the tumor in 3 planes while you treat with stereotactic precision

Transforming your care

Unparalleled opportunity to explore new clinical paradigms

“This is a very exciting innovation in the evolution of radiotherapy, and a great example of re-designing a care experience to get the best possible life outcomes for our patients.”
Keith Hansen, Executive Manager of Oncology, GenesisCare, UK

Reduce margins with certainty

With the ability to visualize the target during treatment and visual confidence that dose is delivered to the target giving you the ability to spare more healthy tissue than ever before

Expand your treatment options

Unity provides an opportunity to manage hard-to-treat cancers and increase treatment options by the ability to visualize daily changes in tumor and surrounding healthy tissue with sub-millimetric resolution and superior soft tissue contrast

Assess tumor response*

Leverage functional MRI protocols to probe radiobiology and potentially detect/assess tumor response with diagnostic quality imaging provided by the state-of-the-art 1.5T MRI

*DWI is CE-marked and 510(k) cleared for brain applications. Intended for imaging purposes.
