Varian Medical Systems Receives 510(k) Clearance for AcurosÂ® XB Advanced Dose Calculation Algorithm for Planning Radiotherapy and Radiosurgery
SAN DIEGO, Nov. 1 , 2010 /PRNewswire-FirstCall/ — ASTRO Booth # 201 — Varian Medical Systems (NYSE: VAR) has received FDA 510(k) clearance for the AcurosÃ‚® XB advanced dose calculation algorithm which can complete a RapidArcÃ‚® treatment plan two to three times faster than conventional planning algorithms. Varian has incorporated the Acuros algorithm for external beam radiotherapy treatment planning into its market-leading Eclipse(TM) treatment planning system on exhibit at the 52nd annual meeting of the American Society for Radiation Oncology (ASTRO) in San Diego October 31 – November 4.
The Acuros dose calculation algorithm is designed for planning complex cases quickly and easily. It is particularly beneficial for planning sophisticated treatments in areas like the lungs or sinuses, where tissue density varies. It is also ideal for planning treatments that require many beam angles, including RapidArc radiotherapy and radiosurgery, which deliver beams continually from all angles as the treatment machine rotates around the patient.
“Acuros XB can reduce the time it takes to compute a typical RapidArc plan for head and neck cancer by up to 60%,” says Corey Zankowski, Ph.D., senior director of product management at Varian. “A savings of 60% in treatment planning time can have a positive impact on the workflow of a busy cancer center.” Acuros will make it possible for clinics to complete plans quickly so that they can start patient treatments earlier.
“Acuros XB utilizes sophisticated mathematics and computing methods to achieve the same level of precision obtained with the more cumbersome Monte Carlo approaches that are too slow and impractical for daily clinical use,” Zankowski says. “This is particularly important given recent trends toward dose escalation and radiosurgical approaches for treating lung and other forms of cancer that require more precise planning.”
“Varian is committed to providing clinicians with tools that make it faster, easier, and more cost effective to offer cancer patients advanced treatments that have the best likelihood of a positive outcome, both in terms of survival and post-treatment quality of life,” said Dow Wilson, president of Varian’s Oncology Systems business.
