TRANSCRIPT
A human care company, Elekta pioneers significant innovations and clinical solutions for treating
cancer and brain disorders. Elekta provides intelligent and resource-efficient technologies
that improve, prolong and save patient lives. We go beyond collaboration seeking long-term
relationships built on trust with a shared vision, offering confidence to healthcare providers and
their patients.
A bold new vision
Clarity™ Soft Tissue Visualization

Clarity segmented structure
Clarity™
Soft tissue visualization
CT simulation is a key part of radiation
therapy workflows, but its limited soft
tissue visualization can inhibit its ability to
characterize target anatomy and surrounding
structures. Tumor motion and changes in size
and shape of soft tissue targets over the course
of treatment compound the need for clear soft
tissue visualization.
Clarity takes soft tissue visualization to entirely
new levels for Radiation Therapy. Easy to learn
and use, Clarity is capable of integrating with
any External Beam Radiation Therapy workflow
and equipment to support simulation, planning
and treatment.
Support for Simulation and Planning Clarity’s hybrid imaging technology allows clinicians to add superior soft tissue visualization to their existing CT simulation without the extra cost and overhead of a dedicated MRI3.
Clarity hybrid imaging is achieved by acquiring Clarity images at the same time as the CT acquisition procedure with the patient in the same RT setup position. This allows CT and Clarity images to be automatically fused
for seamless integration into simulation and planning workflows1.
Clarity’s patented assisted automated segmentation technology supports clinicians in rapidly contouring and defining 3D soft tissue targets and anatomy prior to treatment planning.

Add clear soft tissue visualization to simulation, planning and
treatment workflows
Can be added to any existing CT and linac equipment
No imaging dose and no invasive procedures or markers required
Fast image guidance that uses unique and automated, structure- based matching
Affordable hybrid-imaging with automatic fusion to support contouring of soft tissue anatomy
Why Clarity™?
Support for Treatment In the treatment room, Clarity provides clinicians with fast and accurate soft tissue IGRT that can be integrated with any existing external beam delivery workflow, regardless of the platform and without adding any imaging dose.
Clarity uses unique patented segmentation technology to help define and align target structures to the planned daily setup, based on shape, size and position of the anatomy. This provides accurate, structure-based IGRT without the need for surgically implanted markers.

InnovationBy providing unique soft tissue hybrid imaging with CT at the time of simulation for automated fusion, contouring soft tissue anatomy can be done with added confidence and consistency2.
EfficiencyUsing patented automated soft tissue segmentation technology, target contouring can be done quickly and easily. Clarity IGRT, based on anatomical structures, means fast patient setup for shorter treatment slots. Easy to learn and use, Clarity is fully integrated into any external beam RT workflow.
FlexibilityClarity offers hybrid imaging and soft tissue IGRT with any CT and linac delivery platform, regardless of age or brand and is compatible with all major TPS systems.
EvidencePersistent 3D imaging and anatomy definition data to allow for monitoring target motion, shape and size over the course of treatment.
ConfidenceClear soft tissue visualization at all stages of external beam RT workflows provides clinicians confidence in anatomy definition for planning and confidence to perform daily treatment shifts.
The Elekta commitment to OncologyElekta product and service development is driven by a commitment
to deliver on five core values in order to offer our customers an
enhanced partnership for the fight against cancer. Clarity
delivers against those values in the following ways:
