Eclipse Customers Achieve Top Scores in Treatment Plan Studies

19 of top 20 scoring plans in TROG/ProKnow SBRT Spine Plan Study used Eclipse treatment planning software

Customers using Varian TrueBeam® and/or Edge™ radiosurgery solutions along with Eclipse™ treatment planning software created the top scoring treatment plans in two competitive international plan studies: the 2017 TransTasman Radiation Oncology Group (TROG)/ProKnow Stereotactic Body Radiation Therapy (SBRT) Spine Plan Study and the 201

7 Sun Nuclear QA and Dosimetry Symposium (QADS)/ProKnow Head & Neck Plan Study.

The goal in each study was to create quality treatment plans that were also highly deliverable. In the Spine Plan Study, 19 of the 20 top scoring plans used Eclipse. All nine of the highest scoring plans were created by customers using TrueBeam or Edge systems along with Eclipse.

"I am proud to show the world we can create the best treatment plans right here at Kantonsspital in St.Gallen, Switzerland and having leading edge Varian technology certainly makes it all possible," stated Simon Heinze, who developed the top spine SBRT plan in the TROG study.

The two highest scoring treatment plans in the Head &Neck Plan Study were also created using Varian technology. Physicist Jonathan Stenbeck devised the highest scoring head and neck treatment plan with Eclipse out of 238 participants worldwide with excellent measured quality assurance in terms of the plan's deliverability on the TrueBeam system.

"It was exciting to hear that I created the highest scoring head and neck plan using both Eclipse and a TrueBeam linear accelerator and I was able to show a very close match between the planned and delivered dose, using a Sun Nuclear ArcCheck QA device," said Jonathan Stenbeck, CMD, DABR, Greenville Health System/US Oncology. "It was also fun sharing my planning techniques with the community via ProKnowSystems.com."

In both studies, participants generated treatment plans and submitted them via a cloud-based system called ProKnow. The competition included benchmarking for achievable levels of treatment plan dose quality; analyzing delivery efficiency, variation, monitor unit usage; and sharing of best practices. Plans were scored objectively based on many different target and organ-at-risk metrics and their respective scoring functions. For more info on the studies, visit the ProKnow Systems web site.

"Varian customers are demonstrating time and again that our TrueBeam and Edge delivery systems and the Eclipse treatment planning system together can create the highest quality treatment plans," said Pat Kupelian, vice president of Medical Affairs at Varian.
