ELEKTA ANNOUNCES NEXT-GENERATION RADIATION TREATMENT TECHNOLOGIES AT ESTRO 27

ELEKTA ANNOUNCES NEXT-GENERATION RADIATION TREATMENT TECHNOLOGIES AT ESTRO 27

Gothenburg, Sweden (September15, 2008) -- Elekta, a human care company
pioneering significant innovations and clinical solutions for cancer and brain
disorders, are currently exhibiting several important innovations in radiation
therapy and radiosurgery at the 27th annual meeting of ESTRO, The European
Society for Therapeutic Radiology and Oncology.


The new systems and solutions showcased by Elekta includes;

• Monaco, a next-generation inverse treatment planning system developed by CMS,
part of the Elekta Group, which is now being expanded to include support for
Elekta VMAT (Volumetric intensity Modulated Arc Therapy) 

• Four-dimensional Image Guided Radiation Therapy (IGRT) on the Elekta Synergy®
linear accelerator system.

• Leksell Gamma Knife® Perfexion™ and the EXTEND™ Program for fractionation
support in Gamma Knife surgery.

Monaco VMAT Planning

Elekta has significantly advanced the field of radiation oncology by
dramatically improving on existing IMRT (Intensity Modulated Radiation Therapy)
techniques with Elekta VMAT. So far, the clinical benefits of IMRT have been
tempered by an appreciation of the time it takes to execute highly conformal,
organ-sparing, dose-efficient and optimally therapeutic IMRT plans. Elekta VMAT
(Volumetric intensity Modulated Arc Therapy) overcomes these limitations and has
the unique ability to use single or multiple gantry arcs that sweep non-stop
over the target isocenter, while simultaneously controlling gantry speed,
multileaf collimator leaves, dose rate and collimator angle. Elekta VMAT
promises highly conformal, yet dramatically shorter treatments - as short as 90
seconds. 

The VMAT Planning support on Monaco will represent a fundamentally new approach
to IMRT. The new system, featuring biological modeling, constrained
optimization, and Monte Carlo dose calculation algorithms, including a unique
and sophisticated set of tools will make the radiotherapy planning process
easier, more straightforward and clinically reliable.

4D IGRT on Elekta Synergy®

At ESTRO 27, Elekta is also offering a preview of the recent innovations adding
to the capabilities of the Elekta Synergy® system for Image Guided Radiation
Therapy.

In collaboration with clinical partners, Elekta has developed an innovative and
patented 4DCT (computer tomography) technique to manage the motion for lung and
other tumors inclined to move during treatment. 

Used at the time of treatment, this 4D image guided (with time as the fourth
dimension) process adds a ‘time-lapse' picture to existing 3D volumetric
imaging, producing 3D images that move and adjust over time. This can be used to
register the movement of a tumor during, for example, the respiratory cycle and
eliminate both set-up errors and baseline shifts in the tumor position and
thereby reduce the volume of lung irradiated.

Leksell Gamma Knife® Perfexion™ and the EXTEND™ Program

EXTEND™ is a new treatment program that lets radiation oncologists and
neurosurgeons apply the power of the world famous Leksell Gamma Knife® to
fractionated stereotactic radiotherapy.

With its new re-locatable frame, EXTEND offers maximum stability, enabling the
most accurate, non-invasive localization available and now allows clinicians to
explore the possibility to treat large or critically located targets in the head
and neck that were previously untreatable with Gamma Knife® surgery.

EXTEND is a bridge between the pin-point accuracy of Leksell Gamma Knife
Perfexion and the treatment and fixation options commonly used in radiation
oncology, providing an exciting cross-over solution for neuro-oncology.
