DART | Treatment Process

Dynamic Adaptive Radiotherapy (DART™) is a natural progression from the convergence of IMRT, IGRT, and dose guidance. The Varian™ DART solution places the best planning and treatment tools at the clinician's fingertips through a fully integrated oncology environment.

Dynamic adaptation can be accomplished using existing levels of staff, within normal treatment windows for optimum efficiency. DART lets clinicians evaluate up-to-the-second patient information, adapt the treatment strategy immediately, and manage specific disease sites with specially designed tools. For any patient challenge, DART helps keep treatments right on target.

Localization and immobilization

EXACT® and EXACT IGRT Couch with indexed immobilization

Exact repeat positioning for accurate set up every time
Indexed immobilization reduces set-up times and ensures reproducibility
Movable, carbon fiber support rails allow transition between oblique and posterior treatments without moving the patient
Carbon fiber couch top for high-quality imaging
Remote couch motion allows automated patient repositioning.

Treatment planning

Eclipse™ inverse treatment planning system

Fast efficient planning workflow and standardization using Clinical Protocols and Smart Segmentation enables DART planning in seconds
Automatically optimized dose objective beam orientation improves DART plans in less time
Easy 4D viewing enables planning for organ motion for gated or non-gated treatments
Plan for high resolution on small target volumes using the high-definition multileaf collimator (MLC) with 2.5mm leaf width

Plan verification

Acuity™ planning, verification, and simulation system

Uniquely combines planning, simulation, and motion data for verifying patient plans.
Planned field positions can be automatically set up for a more efficient verification process
With image controlled simulation the localization process is more accurate and efficient
A wide array of integrated in-room imaging tools provides Cone-Beam CT, and radiographic and fluoroscopic imaging.

Treatment delivery

Clinac® linear accelerator

Proven standing wave guide technology for stable dosimetry and high dose rates
Patented energy switch delivers a full range of therapeutic energies at consistently high dose rates
Fastest beam on time to full stability at less than 500 milliseconds
Klystron technology provides the most stable and reliable RF power source
Auto field sequencing means efficiency in treatment delivery

On-Board Imager® with Cone-Beam CT

Fully automated real-time imaging system enables clinicians to pinpoint tumor sites, adjust positioning, and complete a treatment all within the standard timeslot
On-Board Imager operates along three axes of motion for optimum positioning
High precision image tracker shows internal anatomic landmarks and tracks motion
Toolkit includes radiographic 2D imaging, and fluoroscopic and 3D cone-beam CT for fine tuning patient positioning just prior to treatment
Volumetric cone-beam CT provides a high-quality 3D image to help distinguish tumors from surrounding soft tissue and improve tumor targeting

Millennium™ Multileaf collimator

Large DART treatment field at 40x 34cm without moving the patient
Highly accurate leaf positions mean greater precision for dynamic targeting
Exclusive Dynalog files enable the analysis of planned versus actual leaf position
Modify treatment routinely to account for gradual reductions in tumor size

Real-time Position Management™ (RPM) system

Non-invasive automated system synchronizes breathing motion with image acquisition
Radiation beam is gated to when the target falls within the treatment field
Patient can breathe naturally and remain comfortable, increasing compliance
Adjust beam to internal organ movement during treatment with real-time motion management

Quality assurance and verification

DART QA solutions

Faster and easier DART QA reduces time spent on QA
Efficient pretreatment QA compares relative and predicted dose
Quick verification enables analysis and documentation without film
Exclusive Dynalog analysis for instant in depth analysis of DMLC
Achieve the ultimate level of confidence in patient care by validating each treatment with 3D QA plans and portal dosimetry

PortalVision™ Portal imaging

Integrated amorphous silicon imager allows immediate online visual confirmation of patient positioning
Optimal system design for high clinical resolution with compact image files

Image and information management

ARIA™ Oncology Information System

Oncology specific EMR provides instant access to the most current patient information and images
Offline review of images acquired at treatment streamlines the IGRT process and guides future treatment decisions
Enterprise wide connectivity enables automatic updates to the patient chart allowing you to make more informed clinical decisions
