RaySearch dedicates a large share of its revenues
to Research and Development. The two, from the
very beginning, have been distinctly separated.
Development focuses on producing a new
RayStation version every year while Research has
more flexibility to work on long-term innovative
projects without the time of delivery pressure.
RaySearch has always strived to bring the latest
innovation in the field of radiation therapy to
clinical practice. As an example RaySearch’s IMRT
optimization solution, created in 2000, is the
most used worldwide. That same progressive
philosophy has fueled RaySearch and driven the
launch of its own treatment planning platform.
RayStation was therefore developed as the nextgeneration TPS, with a built-in time dimension,
capable of handling not only today’s needs, but
also those of tomorrow such as adaptive therapy.
The system also offers a big potential to automate
several aspects of treatment planning so that you
can spend your valuable time where it is most
needed.
RaySearch believes adaptive planning intelligently
combined with automated planning will bring a
bright future to radiation therapy. As a RayStation
user you can be a part of that future now and
advance cancer treatment with us.
RayStation was the answer to the need for a
treatment planning system (TPS) to handle
adaptive therapy and other advanced techniques.

A WORLD WHERE YOU
ARE IN CONTROL
RayStation has been designed with the user and the workflow in mind. As a user you
feel “right at home” and you can plan in a more intuitive and effective way.
The design speaks for itself, once you try it there is no way back. Well, actually there
is. RayStation features an UNDO/REDO option because we believe you should be
able to jump back and forth through multiple actions.

ONE SYSTEM. ENDLESS POSSIBILITIES.
We optimize for all treatment techniques with our robust algorithms that
account for density and patient setup uncertainties.
rayOptimizer, RayStation’s ultrafast multi-purpose optimization engine, can
solve virtually any posed optimization problem within radiation therapy using
all degrees of freedom of the treatment unit.
3D-CRT
rayConformal provides conventional 3D-CRT, forward treatment
planning, with manual and automatic tools to create conformal
treatment using treat-and-protect, beam weighting, wedges
etc. It also makes modern inverse planning techniques
available for creating conventional 3D-CRT plans. 3D-CRT plans
can be automatically optimized with respect to any
combination of segment shapes, segment monitor units,
collimator, gantry and couch angles. This makes the creation of
high quality 3D-CRT plans faster and more consistent.

IMRT
VMAT
ELECTRON
rayIntensity provides state-of-the-art tools to design and
optimize IMRT treatment plans. Through direct optimization of
step-and-shoot segments, IMRT plans of high quality and with
a minimum number of segments are created. This increases
the overall treatment quality by speeding up both the planning
and delivery process. Conversion for Sliding Window (i.e.
dynamic MLC) IMRT is also supported.
With rayArc, RayStation offers design and optimization of
single or multiple-arc plans. VMAT is planned through an
optimization procedure (inverse planning) where objectives
and constraints for the desired dose are defined, and the
system produces the plan that best matches these criteria
within the limitations of the treatment machine.
That means the optimized plan is directly deliverable with no
quality-degrading post processing required.
With rayElectronPlanning working with mixed electron and
photon plans is straightforward by the application of multiple
coupled or independent beams sets in a single treatment plan.
The Graphical User Interface (GUI) offers a range of useful tools
and a 3D visualization of the treatment setup. With the 3D view
the physical perimeter of the selected applicator, in the patient
geometry, can be inspected to assist the planner in collision
avoidance. The electron module supports automatic
generation of the cutout shape by the same treat and protect
tools used in the 3D-CRT module. The cutout can also be
created and edited by a manual brush tool.
The system is fast and easy to use and gives us the possibility to create
high quality IMRT plans. Our drivers are to provide high quality robust
treatment plans. This is dependent on an efficient workflow. To use time
in a smart way we have to automate things that can be automated. By
employing software to perform standard operations, our specialists can
focus on more creative tasks.”
- Rik Westendorp, Medical Physicist, RISO Radiotherapeutic Institute, Deventer, Holland.
“
Here at L’Hôpital Riviera, RayStation is our sole
Treatment Planning System. Approximately 80% of
our patients are treated with VMAT and we find that
the plans are of excellent quality.”
- Oscar Matzinger, MD, Chief Radiation Oncologist, l’Hôpital Riviera, Switzerland.

REVOLUTIONIZING
COMPUTATION SPEED
With RayStation you benefit from unrivalled computation speed that should
radically transform your treatment planning process.
ACCURATE AND EFFICIENT
CONTOURING
As the computation time is measured in seconds rather than minutes, you can
efficiently produce several competing treatment plans to assess different trade-off
situations instead of opening a second case or going on a break during
computations.
Optimization and clinical dose computation for a standard prostate IMRT case is
done in less than ten seconds and in approximately 30 seconds for a more complex
9-beam IMRT head and neck case on a high resolution 2mm dose grid. *
Depending on the modality, RayStation uses different beam models and dose
calculation engines to quickly and accurately calculate dose. In the latest release
CC-dose algorithms have been rewritten for CPU and GPU to further speed up dose
computation.
We’re talking
SECONDS!
The rayAnatomy module in RayStation contains tools for
creating a rich and accurate representation of the patient
anatomy used in the treatment planning process.

Advanced manual and semi-automatic contouring
RayStation includes a comprehensive tool set for manual
contouring such as polygon, freehand, paintbrush/2D rollerball and local deformations (push-and-pull). It also supports
regions-of-interest (ROI) with voxel-based triangulation, 4D
visualization and boolean algebra for combining ROIs.
Templates can be saved with or without the geometries
included which can then be recalled on future patients.

MBS is a semi-automatic tool for delineation of regions-ofinterest based on biomechanical and statistical information
about organs. Volumetric images are segmented semiautomatically, utilizing a combination of grey-scale g­ radients
and models with knowledge of how organs may change
shape. It is possible to delineate multiple regions of interest
simultaneously which increases throughput, accuracy and
reproducibility.
Atlas-Based Segmentation,
a versatile auto-segmentation tool
The idea is to take existing data from the clinic database to create
templates with multiple image sets – atlases – and use these to
segment new image data by locating the best matching atlas
through rigid image registration and apply deformable registration to
deform the ROI and POI geometries onto the new image set.
The geometries contained in each atlas can be manually contoured
or generated with MBS. If MBS ROIs are available in the template they
may be automatically adapted after atlas-based initialization is
completed. Derived ROIs created from a template will automatically
be updated after initialization and MBS adaptation.
Image Registration/Fusion
Rigid and deformable registration of multi-modality imaging CT, CBCT,
PET or MR is fully supported and integrated. It can be used for
showing fused images as reference while contouring, and for
mapping regions or points of interest between image sets.

EVALUATE CLINICAL TRADE-OFFS
IN REAL TIME
A constant difficulty encountered in radiation therapy treatment planning is the
patient-specific trade-off between ensuring appropriate tumor coverage and
avoiding excessive radiation to healthy structures.
Such trade-offs are conventionally resolved by manually
altering an optimization problem formulation and
re-optimizing the treatment plan multiple times. Trial and
error of this form is time consuming and even if a treatment
plan deemed satisfactory is found, it is not clear if better
treatment options exist for the current patient.
Instead rayNavigator, RayStation’s Multi-Criteria
Optimization’s tool (MCO), generates a set of relevant
treatment plans that are Pareto optimal with respect to the
user-specified set of trade-offs, objectives and constrains.
These Pareto optimal plans are feasible with respect to all
constraints where no objective can be improved without
impairing another one.
Based on these plans, the planner or physician can
navigate sliders in real time to balance between conflicting
clinical goals.
“
The typical trade-off in radiation treatment planning is target coverage versus critical structure sparing. Traditional treatment planning proceeds by a trial and error fashion, where the planner tries
to guess at system optimization parameters that might strike the
best balance amongst the multiple conflicting goals. But this process can be quite time consuming.
Multi-Criteria Optimization simplifies this by presenting the
planner with a set of sliders which allow them to surf across the
trade-off space and quickly decide on the right balance.”
- David Craft, Assistant Professor at the Department of Radiation Oncology,
Massachusetts General Hospital in Boston.
CLINICAL BENEFITS:
• Planners and physicians can find solutions they didn’t know existed
• Physicians tend to select plans with higher OAR sparing at the expense
of slightly under dosing target as they can see exactly where it happens
• The total treatment planning time is significantly reduced without
compromising plan quality
• Planners with limited experience and knowledge can produce clinically
acceptable plans

EXPERIENCE THE FULL POTENTIAL
OF PARTICLE THERAPY
Particle therapy is the most advanced form of radiation therapy and offers
many benefits compared to conventional radiation therapy especially with
respect to conformance of the dose to the target region and sparing of
healthy tissue. RaySearch put strong focus in this area to offer full
optimization of physical dose as well as biological effect of a large variety of
particle therapy types.
The sharp dose distribution, main benefit of proton therapy,
also means that proton treatments are very sensitive to errors
in the patient setup and density calibration. RayStation
includes an elaborate algorithm for robust optimization to
make the treatment plans robust against these uncertainties.
Other issues are interfractional motion resulting in interplay
effects. Evaluation of these effects and methods to mitigate
“
RayStation offers a much needed improvement of the treatment planning
environment for proton radiation therapy. Using RayStation helps us to
improve our efficiency in producing highly optimized treatment plans for our
patients and offer advanced plan evaluation tools to the clinical team.
RayStation has allowed us to ramp up our patient numbers rapidly including
very complex cases at a very early stage of operations. ”
- Niek Schreuder, VP and Chief medical Physicist, Provision Proton Center, Knoxville, Tennessee, USA.
them are crucial, and RaySearch has developed tools for this for this
purpose, such as repainting.
The proton module in RayStation supports a variety of proton
treatment techniques and beam lines, such as pencil beam
scanning (PBS), uniform scanning (US) and double scattering (DS).
rayUniformScanning and rayPassiveScattering provide modern tools
for efficient planning of Uniform Scanning and Double Scattering to help
the user create clinical treatment plans and subsequent milling
machine instructions including the automated creation of
compensators and blocks with manual editing possibilities.
rayPencilScanning provides tools for designing and optimizing actively
scanned pencil beam proton treatment plans like IMPT, single field
uniform dose and distal edge tracking. All plans are directly deliverable
after optimization, since the minimum spot weight is taken into account
in the optimization.
Since RayStation is a complete treatment planning system, that
supports many different modalities, simultaneous optimization with
photons is possible. Also the Fallback planning module provides the
possibility to convert a proton plan into a photon plan ensuring no
interruption in the treatment.

AUTOMATED PLANNING
FOR IMPROVED CARE
FALLBACK PLANNING: TREATMENT
GOES ON NO MATTER WHAT
At RaySearch, we aim to automate parts of the treatment planning process as we truly
believe it will help you improve patient outcome and access to care. We automate standard
procedures so that you can spend your valuable time on complex cases and provide more
personalized care to the patients who need it most.
rayFallback is a tool for creating additional plans to be used in a
contingency situation, enabling a patient to be treated on another
machine, possibly with a different modality and/or treatment
technique, in case the original machine is unavailable.
The fallback plans are automatically generated after plan approval
based on previously created protocols. No user interaction is
required as this is a fully automated plan creation process. If
needed the created fallback plans can still be modified manually
after the automatic generation.
Plans of any modality, including Proton plans and Tomotherapy
plans, can be converted to photon plans with various modalities,
such as; 3D-CRT (rayConformal), IMRT (rayIntensity) and/or VMAT
(rayArc). Fallback planning uses a dose mimicking function to
replicate the DVHs of a given plan, but with a different machine or
treatment modality.
AUTOMATED BREAST PLANNING
RayStation’s automated breast planning solution, rayAutoBreast is the
first step in our ambition to automate standard procedures.
rayAutoBreast was initially developed at Princess Margaret Hospital
(PMH) in Toronto, Canada. Between 2009 and 2012, PMH ran a largescale clinical study to evaluate the performance of their automated
treatment planning methodology for tangential breast intensity
modulated radiation therapy (IMRT). Automated planning was used in
97% of the patients receiving tangential breast IMRT during the time
interval studied i.e. in 1661 patients. In their study results, PMH
observed an increase in clinical acceptance using this fully automated
method. They conclude that the method can add tremendous
efficiency, standardization, and quality to the current treatment
planning process and that its use will allow faster adoption of IMRT
together with increased access to care improvements for breast cancer
patients.1
The rayAutoBreast module provides tools for automated generation of
tangential breast IMRT plans using heuristic optimization and includes
features such as:
• Automatic detection of radio-opaque markers defining the breast
• Automatic contouring of all the relevant target and risk organs
• Automatic setup of beams, including heuristic optimization of
gantry and collimator angles
• Automatic creation of objective functions, optimization and
segmentation settings and clinical goals
1. T.G. Purdie et al., “Automated Planning of Tangential Breast Intensity-Modulated
Radiotherapy Using Heuristic Optimization”, Int.J. Radiation Oncology Biol.Phys.Vol. 81,
No.2, pp. 575-583, 2011.
After creation, the fallback plans can be compared and evaluated
using a number of visual tools (DVH curves, dose statistics, dose
difference and clinical goals). A fallback plan can then be approved
and used for delivery in future fractions. It is also possible to
convert back to the original plan, in case the original machine is
repaired.
Finally, with dose summation tools, two plans can be combined
using their delivered fractions so that actual composite dose can
be visualized on the patient data set. The Fallback planning
module can drastically reduce planning time in emergency
situations when a machine is down allowing the patients´
treatment to continue and reducing stress on staff.
Fallback planning can also be used to validate the modality
selected for treatment, assuring that the most efficient approach
is utilized for each patient.
PLAN GENERATING PROTOCOLS
RayStation supports several tools such as templates and plan generation protocols to automate
parts of the planning process. A protocol is a list of plan generation steps which can be applied
automatically. Examples of plan generation steps include atlas based segmentation, plan
creation, set dose grid resolution, add beams, add optimization functions and add optimization
settings. When a protocol is run it will automatically create a plan using the included steps, which
drastically reduces the planning time.

TAKE THE RADIOBIOLOGICAL
EFFECTS INTO ACCOUNT
EVALUATE YOUR PLANS SMOOTHLY
AND SIMULTANEOUSLY
The use of radiobiological response models brings the planning process closer to
the intent to create a plan with the highest possible probability of curing the
patient while keeping the risk of complications to the surrounding healthy tissue
as low as possible. The philosophy is to use the biological models to reveal effects
that are difficult to understand from the dose distribution alone.
rayBiology provides tools for both biological optimization and evaluation.
Optimization tools provide the ability to optimize directly on the biological
indices in combination with physical dose-based optimization functions. It
makes it possible to configure optimization problems which more closely
describe the clinical intentions, such as minimizing normal tissue complication
probabilities subject to a guaranteed homogenous target dose within a
specified standard deviation.
rayEvaluation is a comprehensive toolbox for evaluation and comparison of
treatment plans and plan approval. From a number of predefined layouts, dose
distribution, dose statistics, clinical goals and dose volume histograms of up to
three different plans can be simultaneously compared.
Dose can directly be computed on additional image sets and summed up using the
deformable registration provided in rayDeformable. For evaluation of robustness
dose can also be computed for a density perturbation or isocenter shift.
Evaluation tools includes Tumor Control Probability (TCP) and Normal Tissue
Complication Probability (NTCP) models which can be combined with tissue
repair and tumor growth models.
The biological tools are integrated in the plan evaluation module. That way the
physical properties of the existing plan can easily be investigated if
unexpected differences in the biological response are observed between
different plans. In addition there is a Biological Evaluation module dedicated
to the exploration of the biological effects of altering the fractionation
schedule of a single treatment plan.

IMPLEMENT ADAPTIVE
RADIATION THERAPY TODAY
RayStation was designed from the very beginning with a strong focus
on handling the dynamic aspects of radiation therapy. By explicitly
representing the time dimension throughout the domain model,
RayStation provides the ultimate framework for planning and managing
adaptive radiation therapy.
When images of the patient in treatment position, from CT, PET/CT,
cone-beam CT or MR, are acquired during the treatment course,
rayDeformable makes it possible to establish a deformable
registration between the new geometry and the planning
geometry.
Plans can then be re-optimized and adjusted to compensate
for dose coverage problems or to adapt to adjusted clinical
goals. The replanning options range from simple adaptations
such as adjustments of beam weights to complete replanning
that involves reoptimization of the intensity modulation.
Through rayTracker, this can be used to recalculate, deform and
accumulate doses from different fractions in a common
geometry, thereby computing the dose delivered to the patient
anatomy.
RayStation’s adaptive re-planning tools, combined with
powerful deformation algorithms, can improve your planning
process. These tools allow for more accurate treatment for
your patients.
If there are deviations from the planned dose distribution that
require action, rayAdaptive provides a wide range of adaptive
offline or online replanning tools that take into account the
accumulated dose and observed deviations of the patient
geometry.
18
“
By implementing adaptive radiation therapy we can further
improve the precision in our treatments. This requires very
sophisticated software tools and RayStation really stands out
as the best treatment planning solution on the market for adaptive therapy. I see this as a starting point of a deep collaboration
with RaySearch for both clinical and research applications.”
- Karsten Eilertsen, MD, Head of Radiotherapy Physics,
Oslo University Hospital

SCRIPTING: YOUR IMAGINATION IS THE LIMIT
Scripting in RayStation provides automation,
connectivity and flexibility beyond the
standard user interface.
The script language, IronPython, is a complete programming language that
let the user access all capabilities of the operating system and other
applications, for instance to write files, start processes, communicate with
other computers, and control other scriptable applications such as
Microsoft Office or .NET.
Automation
Through scripting, the clinic specific procedures can be automated. For
instance, a script can check for properties in a plan such as small
segments, disconnected target volumes, hotspots, undesirable gantry and
couch angles, and based on this information, display a warning message or
create a report.
“
Our commissioning results were within 2% at 2mm, well within
the industry standard. When I work on beam commissioning
in RayStation I remember why we bought it. The results are so
beautiful, it makes me happy to be a physicist.”
-Patricia Sansourekidou, Medical Physicist, Health Quest Radiation Oncology.

Connectivity
Scripting provides a way to customize the interaction between RayStation
and other systems for scenarios where DICOM is not sufficient.
Flexibility
Scripting can be used to create capabilities which are not
specifically available in the standard interface. For instance, automatic
marker detection, export of images of non-standard dose planes and
images of all control points can be utilized as desired. Scripting puts power
in the hands of the clinicians to use RayStation in a way that best serves
the needs of their department.
Scripting on multiple patients- a potential research tool
Through its ability to execute over multiple patients, scripting is an ideal tool
for retrospective data analysis and for evaluating new treatment
techniques. For instance, a script can go through a cohort of patients and
systematically alter some parameter and record the effect or just extract
data such as dose statistics.
20
“
Full compatibility with any existing modality
and complete hardware independence
RayStation is compatible with all linear accelerators commercially
available.
RayStation’s data model is fully compatible with the DICOM standard,
allowing the system to easily import and export any DICOM RT object.
This includes m
­ ultiple CT, MR and PET image series, 4D-CT, structure
sets, doses and RT Plan and RT Ion treatment plans. In addition,
RayStation communicates with other data sources such as IHE RO,
DICOM senders and receivers or DICOM archives, using either file
transfer, DICOM storage service classes or DICOM query/retrieve.
Akron General was able to streamline these processes
while also avoiding human input errors, making the
entire process less intense and time-consuming on
the dosimetrist.”
RayStation includes accurate and fast dose calculation services for any
treatment modality. In the latest version, dose calculation speed has
been increased further by utilizing the GPU. A dedicated graphical user
interface rayPhysics is available for photon and electron modeling. This
workspace allows for evaluation of models as well as treatment
planning tools prior to commissioning a machine.
Quality Assurance
The module for Quality Assurance preparation allows the user
to easily transfer the clinical plan to a phantom and recalculate
dose, either beam by beam or for the entire plan. The output
from the module is the dose distribution in DICOM format or a
2D dose plane, a QA report and optionally a new treatment plan
with collapsed gantry angles.
Key Features
• Collapsed cone photon dose calculation engine for high
accuracy
• Singular value decomposition photon dose calculation
engine for real-time purposes
• State-of-the-art direct Monte Carlo code for electrons
• Highly optimized proton pencil-beam algorithm with
