Visualize the target and OARs with certainty

With the versatility of a library of optimized, anatomy specific imaging sequences, you have the right options for each patient to visualize the target and OARs clearly and with certainty

See difficult to visualize structures

Our imaging sequences, optimized for high contrast, high resolution and speed will allow you to even see difficult-to-visualize structures. See small oligomet nodes, low contrast lesions, intra-prostatic lesions, urethra, neuro-vascular bundle and seminal vesicles clearly

Improve local control

Elekta Unity combines accurate, diagnostic quality MRI with precise radiation delivery—a unique combination which provides superior soft tissue visualization of the relationship between the tumor and surrounding anatomy allowing you to confidently escalate daily dose.

The escalated treatment dose is focused on the tumor at every moment, leading to increased protection of healthy tissue and providing opportunities for better outcomes and fewer side effects.

Reduce toxicity

Advanced organs at-risk sparing

The Unity system’s unparalleled accuracy helps you to reduce margins without risk to healthy tissue, increasing dose effectiveness while decreasing side effects

Onboard 1.5T MRI allowed us to visualise and target a recurrent seminal vesicle lesion which would have remained occult on CT. We were confident we were treating the lesion and could do so with a reduced PTV margin.

Treat more patients with simplified and intuitive MRgRT stereotactic radiotherapy

  • Unity opens up the possibility of shorter treatment courses through hypofractionation and fast MRgRT fraction times
  • Unity is a high productivity system and can deliver SBRT treatments in 25 minutes
  • For prostate cancer, for example, Unity can deliver stereotactic treatments in just 2 fractions

Using ultra-hypofractionated MR-guided radiotherapy you are able to deliver prostate treatments in just two fractions*
