Technique shows promise of earlier quantification of a brain tumor’s responsiveness to radiotherapy

Investigators at Sunnybrook Research Institute (Toronto, Canada) are the world’s first to employ – on their 1.5T Elekta Unity system – a sophisticated MRI technique called chemical exchange saturation transfer (CEST) for patients with central nervous system (CNS) tumors. Using the CEST MRI pulse sequence periodically during a radiotherapy course could help clinicians better understand…

Tailor-made treatment fit Lyn like a glove

For many people, Lyn’s life sounds enviable. Together with her husband of 45 years, she enjoys the year-round gentle climate that Sydney, Australia, offers; perfect for making the most of the outdoors. Lyn’s a proud mom of three grown daughters, but her real pride nowadays is her six grandchildren, who she spends as much time…

AI technology to simplify Unity prostate workflow

Elekta AI-assisted auto-contouring, currently under development, has been shown to reduce online prostate contouring time to under two minutes, which will shave around 10 minutes off the current Unity prostate workflow. Such future time savings will help to further enhance treatment accuracy by lowering the risk of anatomical movement during the session and will improve…

MR-guided radiotherapy a new non-invasive option for bladder cancer patients in Australia

The bladder can change in position, shape and size during radiotherapy treatment sessions depending on the organ’s filling rate. This has required clinicians using a conventional linac to use large margins that include normal tissues, an undesirable but necessary practice to avoid a geographical target miss. With their Elekta Unity MR-Linac, however, GenesisCare radiation oncologists…

Paper on first Elekta MR-Linac patient treatments earns award for most citations in physics journal

The intense interest in the potential of MR-guided radiation therapy spurred researchers to cite – in great numbers in Physics in Medicine & Biology (PMB) – a paper describing the 2017 first-in-human proof-of-concept study involving the prototype of Elekta Unity, the world’s first high-field (1.5T) MR-Linac. The 217 citations of the paper: “First patients treated…

Elekta Unity patients can sigh a breath of relief with new imaging upgrade

It was already the most advanced magnetic resonance radiation therapy (MR/RT) system in the world when launched in 2018, nevertheless, Elekta’s MR-Linac, Elekta Unity, continues to evolve, and further sets us apart from our competitors. Motion related image artifacts are a common challenge with free-breathing MRI. The latest product release on Elekta Unity enables 3D…

MR guidance and hypofractionated RT for prostate cancer a good match

Clinicians at the Froedtert & the Medical College of Wisconsin Clinical Cancer Center at Froedtert Hospital and the University of Iowa (UI) are using their respective center’s Elekta Unity MR-Linac system in ongoing efforts to validate the equivalence of hypofractionated prostate cancer regimens to standard fractionation schedules. Although data on the late toxicity of hypofractioned…

Busy Elekta Unity MR-Linac clinical users pile up clinical evidence during pandemic

By Marco Luzzara, MSc, Senior Director of Medical Affairs and Clinical Research, Elekta As virtual events go in 2020, we couldn’t have been more pleased with the quality and volume of presentations at the September 7-11 Elekta MR-Linac Consortium meeting, which boasted an online gathering of a record 566 attendees from 48 sites and 18…
