3D water phantom for faster scanning
Building on the proven Blue Phantom2, Blue PhantomHelix facilitates fast and precise commissioning and QA work, specifically optimized for TomoTherapy®.
Achieve efficient measurements and analysis with myQA Accept. Designed for all 3D scanning needs, it ensures the fastest, most accurate, and most reliable results in your commissioning and QA tasks.

Innovative & independent QA to maximize patient safety
Blue PhantomHelix is powered by myQA Accept, our trusted and well-established software, providing the following benefits:
- Validation of pre-commissioned machines
- Pre-configured beam data validation
- QA of your existing beam models (TPS QA)
- Compatible with any TPS exporting in DICOM format

Optional Rotating Table
- Designed to enable the rotation of Blue PhantomHelix and Blue PhantomCOMPACT 2D water phantom systems
- Easy rotation of the filled water phantom for in-plane and cross-plane measurements; avoids the need to drain the water phantom
- Supports seamless manual rotation of the phantom and exact indexing lock fixation at 0°, 45°, 90°, etc.
- Supports measurements inside the Varian Halcyon®/Ethos™ bore and also suitable for use with conventional linac measurement sessions
Seamless rotation of your 2D water phantom
