their patients.

A bold new vision

Clarity™ Soft Tissue Visualization

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.

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
