Faster arc-based method could help increase the number of patient treatments per day

ODENSE, Denmark, March 18, 2010 - Odense University Hospital (OUH, Odense, Denmark), a major
multi-specialty medical center serving southern Denmark, joined the global
community of Elekta VMAT
( clinical
sites last fall when it began treating patients with the arc-based technique.
With Elekta VMAT, single or multiple radiation beams sweep in uninterrupted
arc(s) around the patient, significantly reducing treatment times.

Shorter prostate treatment

OUH physicians used Elekta VMAT for the first time to treat a patient
with prostate cancer. Because Elekta VMAT enables the treatment beam to
complete non-stop therapy arcs, clinicians were able to perform the one-arc
treatment in a 10-minute session, shaving two minutes off the time needed to
conduct an advanced IMRT (Intensity Modulated Radiation Therapy) treatment.

"The time-savings over successive Elekta VMAT cases could help us treat
additional patients per day," says Knud Aage Werenberg, head physicist at
OUH. "We would like to offer VMAT as the standard treatment for selected
patient groups before this summer."

The two-minute decrease in treatment time may also reduce the chance that
the patient or tumor will move during the treatment session, he adds.

In a study, OUH established Elekta VMAT's speed and quality versus IMRT
several months before the Danish medical center initiated its clinical VMAT
program.(1) "We generated Elekta VMAT plans for 25 patients with head and
neck cancer," he says. "The results showed that the Elekta VMAT target
coverage and sparing of organs-at-risk would be equivalent or superior to the
IMRT plan, while reducing beam-on time by 35 percent."

OUH has used the technique to treat an additional 11 patients, with
prostate, head and neck and lung cancers.

Presently, OUH delivers Elekta VMAT on one of its four Elekta Synergy(R)
( treatment systems. The center operates two
additional Elekta linear accelerators and two treatment machines from another
provider. OUH treats approximately 180 patients daily on these eight systems.
