August 11, 2014 — Elekta’s Leksell Gamma Knife Perfexion radiosurgery system took the first place ranking for the fourth consecutive year in KLAS research firm’s recently released 2014 Best in KLAS Awards: Medical & Infrastructure report. In addition, Elekta’s Agility 160-leaf multi-leaf collimator (MLC) and Elekta Infinity radiation treatment system earned second and third place.
In the report, Perfexion scored 94.5 out of 100 on the system’s functionality and upgrade capacity. Perfexion also scored between 90.5 and 93.5 on four other performance categories, including service and support, and implementation and training.
Further documenting the superior dosimetric performance of Perfexion, a recent multicenter study  showed that the system offers dramatically lower radiation dose to normal brain — in the treatment of multiple metastases — than other systems, such as Varian’s TrueBeam flattening filter-free linear accelerator with a 2.5 mm MLC. Patients with multiple metastases, the report said, stand to receive as much as a 74 percent lower radiation dose to normal brain tissues if the lesions are treated with Perfexion versus contemporary linear accelerator-based stereotactic (SRS) systems.
KLAS surveys include opinions of thousands of health care professionals The KLAS awards are based on data from customer surveys of hospital and clinic executives, administrators, physicians, nurses and other directors and managers interacting with health care equipment and infrastructure solutions.
According to KLAS, Best in KLAS designations go to solutions that have excelled in their respective market segments, that show the vendor’s leadership in working with customers to resolve issues and match expectations to reality, and that have the broadest operational and clinical impact to health care organizations.
The Best in KLAS designation recognizes vendors for their outstanding efforts to help healthcare professionals deliver better patient care. This award is reserved for those that lead the imaging equipment segments with the broadest operational and clinical impact on healthcare organizations.
“This is a tremendous achievement because each of the top performers earned this recognition through the voice of their provider customers,” says Matt Terry, vice president of medical equipment and imaging research for KLAS. “Given that vendors must concern themselves with the complexities of a dynamic health care market and operational challenges, it is remarkable to see so many undeviating from their focus on helping providers succeed.”
