ScandiDos – Precision Visualization in Radiation Therapy QA with TeeChart for .NET

About Us

ScandiDos AB, headquartered in Uppsala, Sweden, is a globally recognized medical technology company focused on quality assurance and dosimetry solutions for radiation therapy. Founded in 2002, ScandiDos has grown into a leader in delivery-verification systems that ensure patient treatments get the right dose of radiation at the right time and place — a mission essential to safety and outcomes in cancer care.

Their flagship Delta4 Family of products combines sophisticated hardware phantoms with powerful software to support pre-treatment plan verification, in-treatment dose measurement, secondary dose calculation and comprehensive machine QA. These solutions are deployed in over 800 clinics across more than 55 countries worldwide.

What is Delta4 and Delta4 Software?

The Delta4 ecosystem delivers a full spectrum of quality assurance tools that medical physicists and clinicians rely on to confidently verify complex radiotherapy plans such as VMAT, IMRT, SBRT and adaptive therapies.

On the software side, the integrated Delta4 Software Platform provides a unified environment for importing treatment plans, analysing measurement data, tracking trends and generating clear, customizable QA reports across all Delta4 modules. It supports:

• Automated processing of treatment plan data and measurement results.
• Clear visual displays of dose deviation, distance-to-agreement (DTA), gamma pass rates and more — all essential indicators for clinical QA.
• Optional modules like Delta4 Machine QA, Delta4 Insight (independent Monte Carlo secondary dose calculation) and Delta4 Statistics Module, delivering deeper analytics and trend insights over time.

This software plays a pivotal role in translating complex radiation measurements into actionable, clinically meaningful information — and that’s where visual components like charts and graphs are indispensable.

How TeeChart Enhances Delta4 Software

Charting and visual analytic components are intrinsic to high-quality QA workflows, helping users interpret vast sets of data quickly and accurately. TeeChart for .NET equips ScandiDos developers with powerful charting tools that:

• Visualize complex multidimensional data — such as dose comparisons, trends over time and statistical breakdowns.
• Offer interactive charts and dashboards for dynamic exploration of QA results, trend graphs and gamma index analysis.
• Support rich customization and export options, enabling clinics to include graphical elements directly in reports and workflows.

By embedding TeeChart into Delta4’s environment, ScandiDos delivers interfaces that are both intuitive for end users and robust under heavy clinical workloads — improving data clarity for pulse-by-pulse dose verification, plan comparison and long-term performance tracking.

Benefits of the Integration

1. Clinical Confidence Through Clarity
   In radiation therapy QA, clarity isn’t a luxury — it’s a necessity. The combination of Delta4’s precise measurement systems and TeeChart’s rich visualizations gives physicists high-fidelity insight into system performance and treatment plan accuracy. Graphs that clearly show deviations or pass/fail criteria enable fast interpretation, safer clinical decisions and more confident patient care.

2. Faster Workflow, Better Decisions
   Delta4 software automates critical parts of the QA process. TeeChart’s smooth, responsive charting helps users instantly see trends, pinpoint anomalies and generate reports without manual re-plotting or external tools — a meaningful time saver in busy clinical settings.

3. Long-Term Data Insights
   With optional modules like the Delta4 Statistics Module, clinicians can visualize trends over months or years to forecast machine behaviour and detect subtle changes, informing preventive maintenance and continuous quality improvement. TeeChart’s visualization engine makes these long-range trends accessible and actionable.

Looking Ahead

As ScandiDos continues to innovate with new modules such as the Monte Carlo-powered Delta4 Insight and advanced machine QA solutions, data visualization remains a central pillar of their software strategy. Clear, precise charts are not merely visual enhancements — they are a vital link between complex measurement data and confident clinical decision-making. By transforming raw data into meaningful, actionable insight, ScandiDos delivers software that not only performs at the highest technical level, but also communicates results with clarity and confidence.
