Eclipse Users Win Top Honors at Treatment Planning World Championships

Professionals using Varian’s Eclipse™ treatment planning software placed the highest in the overall category in the first ever World Championships of Treatment Planning, hosted by ProKnow, LLC. In addition to the top four and six of the top 10 positions in the overall category, Eclipse customers also produced the top three scoring volumetric modulated arc therapy (VMAT) plans.

Physicist Jonathan Stenbeck of the Greenville Health System utilized Eclipse to win top honors in the overall category, which was a combination of plan score and dose QA. "I am honored to have been awarded the highest overall scoring plan in the first World Championship of Treatment Planning," said Stenbeck. "With a time limit of only four hours to complete and submit the plan, it was exciting, but by utilizing Eclipse I was confident I could create a high-quality plan."

Professionals from over 30 countries all competed at the same time and were given four hours to create treatment plans, score them online, and submit their best effort. A description of the body site, physician prescription, and the plan scoring algorithm were provided to participants in advance, and plan scoring was unbiased and objective, powered by the cloud-based ProKnow system.

"This World Championship is just the latest example of how Varian customers can harness the capabilities of Eclipse to deliver the highest quality treatment plans," said Ed Vertatschitsch, vice president, Global Portfolio Solutions. "Congratulations to Jonathan on his accomplishment and to ProKnow for creating a unique competition that allows the cancer care community to share planning techniques that could help raise the level of care around the world."
