CA-based medical instruments maker,
Varian Medical Systems, Inc.
) recently revealed that its Edge radiosurgery system is capable of
delivering sub-millimeter isocenter accurate doses while treating a
targeted tumor. The same was substantiated by medical researchers
from the Portugal-based Champalimaud Centre for the Unknown.
VAR's Edge radiosurgery system is a fast, precise and non-invasive
alternative to conventional surgery for the treatment of patients
with lung, prostate, spine and brain tumors. The system allows
clinicians to destroy tumors from outside the body using
VAR's Edge radiosurgery suite, unveiled by the company in Oct 2012,
consists of many integrated subsystems for planning and delivering
advanced radiosurgery treatments. It comprises patient positioning,
image guidance, beam shaping, real-time tumor tracking and dose
While each of these systems is very precise in itself, VAR
demonstrated that the system as a whole can be accurate to less
than a millimeter while delivering doses. This is highly
advantageous while delivering high doses to tumors near critical
organs and structures within the body.
In Jan 2013, VAR's Edge radiosurgery suite received 510(k)
clearance from the U.S. Food and Drug Administration. Subsequently,
in Sep 2013, Champalimaud Centre for the Unknown and Henry Ford
Health System became the first institutions to install VAR's Edge
radiosurgery suite in Europe and North America, respectively.
Researchers from the Champalimaud Centre and the Henry Ford Health
System will be making seven scientific presentations about VAR's
Edge System at the American Association of Physicists in Medicine
(AAPM) meeting in Austin, TX from Jul 20-24.
Presentations by the two teams will mainly focus on early adopters'
work with VAR's Edge radiosurgery system. The presentations will
also cover a wide spectrum of clinical issues ranging from the
accuracy of patient set-up for image-guided intracranial
radiosurgery to methods for accurately commissioning a new Edge
According to the company, these teams are demonstrating superior
capabilities of the Edge system while figuring out and documenting
best practices for others to follow. In 2013, VAR announced its
decision to launch The Edge Advisory Board, in order to partner
with thought leaders in radiosurgery, including neuro- and thoracic
surgeons as well as radiation oncologists, to support clinical
education and advance standards of care.
