RayStation® 2.5 released

RayStation® 2.5 released

RaySearch Laboratories AB announces that version 2.5 of RaySearch’s RayStation®
treatment planning system has been released for clinical use in Europe and USA
and is pending regulatory approval in Canada. The new version includes a wide
range of new features and improvements.

RayStation® 2.5 includes all of RaySearch’s market-leading optimization
algorithms for VMAT, IMRT and 3D-CRT alongside a comprehensive set of tools for
traditional 3D-CRT planning. This means that the system can be used clinically
for treatment planning of all various treatment modalities of photon therapy.
RayStation® 2.5 also has full support for combining all of these techniques in
the same treatment. In addition, the new version includes improvements of
RaySearch’s unique multi-criteria optimization (MCO) solution for IMRT. This
highly intuitive tool lets the clinician evaluate the impact of changing
different treatment priorities in real-time, which has a large potential to
speed up the time-consuming treatment planning optimization process. The MCO
solution has been developed in collaboration with Massachusetts General Hospital
in Boston, USA.

From the start, RayStation® was designed to handle 4D adaptive radiation therapy
and the new release includes groundbreaking features in this field. Using
advanced deformable registration algorithms, RayStation® 2.5 allows the users to
perform dose tracking. This offers the possibility to perform accurate dose
accumulation of any delivered or planned dose to any patient geometry using any
combination of CT, MR, PET and 4D-CT data sets. RayStation® is the first
treatment planning system that lets the clinicians monitor the impact of a
changing patient geometry as the treatment progresses, and seamlessly adjust the
treatment in the same system. The dose tracking functionality has been developed
in collaboration with Princess Margaret Hospital in Toronto, Canada and is
available for installation in Europe but is pending regulatory clearance in USA
and Canada.

In addition to the new features, RayStation® 2.5 includes major improvements and
performance enhancements that further facilitate and speed up the treatment
planning process. For example, the collapsed cone clinical dose engine has been
reimplemented, now offering unmatched speed, and the DICOM communication
capabilities have been further improved. Examples in the usability area include
extensive use of templates throughout the system, unlimited undo functionality
and all sorts of keyboard shortcuts that are expected in modern software.

“We are very proud that we now can offer the first complete version of
RayStation®. The system is now ready to be the workhorse for all photon
treatments for all types of clinics, from smaller ones to large university
hospitals with very advanced needs”, says Johan Löf, CEO of RaySearch.

“We have a long-standing reputation of excellence in the field of optimization
and firmly believe that we have now taken the lead in the field of adaptive
therapy as well. I am convinced that the combination of optimization and
adaptation is the future of radiation therapy and we fully intend to stay in the
forefront of this development. We will continue to work closely with our
customers and research partners to build new features and refine the system at a
very high pace”, concludes Johan Löf.
