  • SunCHECK: Complete Guide to QA in Radiotherapy

    SunCHECK from Sun Nuclear is the most advanced quality assurance (QA) management platform for radiotherapy departments. Used globally, this solution integrates all quality control workflows into a single interface, eliminating the need for multiple scattered applications.

    If you work in radiotherapy and are looking to optimize your QA processes, this comprehensive guide will help you understand all the features and benefits of the SunCHECK system.

    What is SunCHECK?

    SunCHECK is a unified radiotherapy quality management platform developed by Sun Nuclear Corporation. This solution was designed to simplify and automate QA processes for both equipment (Machine QA) and patients (Patient QA).

    The platform serves as a shared workspace for the entire team, regardless of equipment, machines or organizational structure of the department. This promotes process standardization and facilitates collaboration between medical physicists, dosimetrists and radiation therapists.

    SunCHECK Modules

    The SunCHECK system is divided into two main modules, each targeting specific aspects of quality control in radiotherapy.

    SunCHECK Machine – Equipment QA

    The SunCHECK Machine module (formerly known as SNC Machine) automates quality control of linear accelerators and other radiotherapy equipment. Key features include:

    • Automatic beam parameter verification
    • MLC (multi-leaf collimator) analysis
    • Automated Winston-Lutz tests
    • Daily, monthly and annual quality control
    • Integration with devices such as Daily QA 3 and SRS MapCHECK
    • Automatic reports and complete traceability

    SunCHECK Patient – Patient QA

    SunCHECK Patient integrates all phases of patient QA into a single workflow:

    1. Plan Checks

    Automatic verification of treatment plan parameters, including dose limits, organ at risk constraints and compliance with clinical protocols (RTOG, QUANTEC, etc.).

    2. Secondary Calculations

    Independent dose calculation through the DoseCHECK algorithm, validating the results of the primary planning system.

    3. Pre-Treatment QA

    Verification of plan delivery before the first treatment, with ArcCHECK integration and 2D/3D gamma analysis. Compliant with AAPM TG-218 recommendations.

    4. PerFRACTION – In-Vivo Monitoring

    The PerFRACTION module uses EPID (Electronic Portal Imaging Device) data for real-time dosimetric monitoring during each treatment fraction. This system enables:

    • Detection of patient positioning errors
    • Verification of correct beam delivery
    • Calibrated absolute dosimetric QA
    • Complete automation without additional physicist time

    SunCHECK Benefits vs Traditional Methods

    Adopting SunCHECK brings significant advantages compared to traditional QA methods:

    Automation and Efficiency

    Published studies demonstrate that the PerFRACTION system enables daily patient QA without requiring additional physicist time, making monitoring of each treatment viable. Processes that previously required hours of manual work are now executed automatically.

    Data Centralization

    All QA results are stored in a central database, eliminating scattered files and facilitating audits. Web browser access allows data consultation from any computer on the network.

    Analysis Standardization

    With over 70 preconfigured protocols and common analysis tools for all phases of QA, SunCHECK promotes consistency and reduces inter-operator variability.

    Security and Data Protection

    Sun Nuclear guarantees robust data protection, with flexible installation options that relieve IT teams from asset management and continuous maintenance.

    Clinical Applications in Europe

    Radiotherapy centers across Europe face specific challenges that SunCHECK helps solve:

    • Growing treatment volume: Automation enables maintaining quality with limited human resources
    • Advanced techniques: VMAT, SBRT, SRS and HyperArc require more rigorous QA that SunCHECK facilitates
    • Regulatory requirements: Automatic documentation for compliance with European directives and national standards
    • Multiple equipment: Centralized QA management for different accelerators and manufacturers

    Integration with Sun Nuclear Equipment

    SunCHECK natively integrates with the entire range of Sun Nuclear devices:

    • ArcCHECK: 3D cylindrical phantom for IMRT/VMAT QA
    • Daily QA 3: Automated daily QA system
    • SRS MapCHECK: High-resolution QA for radiosurgery
    • IC Profiler: Beam profile analysis
    • 3DVH: 3D dose reconstruction and DVH analysis

    Frequently Asked Questions about SunCHECK

    Is SunCHECK compatible with all linear accelerators?

    Yes, SunCHECK is compatible with accelerators from all major manufacturers, including Varian, Elekta and Siemens. The system adapts to the specific technologies of each equipment.

    How long does system implementation take?

    Typical implementation takes 2 to 4 weeks, including installation, configuration, validation and team training. Sun Nuclear and authorized distributors provide full support throughout the process.

    Does PerFRACTION completely replace pre-treatment QA?

    PerFRACTION complements pre-treatment QA, offering continuous verification throughout the treatment course. Many centers use both modalities for maximum safety.

    What training is required to use SunCHECK?

    The system was designed to be intuitive, but complete training is provided during implementation. The web browser-based interface facilitates adoption by the entire team.
