Eclipse(TM) Treatment Planning Software from Varian Now Offers Robust Optimization and Proton Therapy Dose Calculation Tools


The latest software release, including the Acuros® proton therapy algorithm for faster, more accurate dose calculation, receives FDA 510(k) clearance



PALO ALTO, Calif. – Varian Medical Systems (NYSE: VAR) has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for the latest release of the company's Eclipse™ treatment planning software, which now incorporates the Acuros® PT advanced dose calculation algorithm for faster, more accurate proton therapy treatment planning.



Other enhancements to the Eclipse software include robust planning and optimization tools that enable proton treatment planners to account for uncertainties connected with patient setup error, tumor motion during treatment, as well as the heterogeneity of tissues surrounding the tumor. The new release also enables users to create scripts that expedite planning functions, quality assurance, data mining, and research.



The Acuros PT dose calculation algorithm is designed to improve the accuracy of the proton dose calculation, especially in regions of the body where the tissues vary in density such as the lung, where air, bone, and soft tissue are in close proximity. The algorithm also considers the density of the treatment accessories/beam shaping devices being used, and enables planning for treatment at the wide range of energies used depending on the depth of the tumor within the body.  Proton planning in Eclipse using the Acuros PT algorithm takes significantly less time than was previously required using other methods.



"Acuros PT is the next innovation to come out of the acquisition of Transpire, Inc. last year," says Jeff Amacker, senior director of clinical solutions. "It brings the benefits of the sophisticated computing methods that Acuros imparted for conventional radiotherapy and brachytherapy to the world of proton planning." 



Eclipse is the market leading radiotherapy treatment planning software, in use at some 3,400 cancer treatment centers worldwide.  "These recent enhancements make it simpler, faster, and easier to use Eclipse to plan highly accurate proton therapy treatments using the same interface, in a software environment that interfaces seamlessly with Varian's ARIA® oncology information system—a platform that many Varian customers use to manage clinical and administrative processes in their cancer clinics," Amacker said.
