RUBY

The New Modular QA Phantom

SYSTEM QA • LINAC QA • PATIENT QA

The phantom that fits your changing needs.

Perform integrated tests of the entire treatment chain from imaging to treatment planning and verification with one basic phantom. Add and expand QA capabilities when needed.

As the new modular phantom platform for radiotherapy QA, RUBY comes with a variety of exchangeable, application-specific inserts that satisfy all test requirements in a modern treatment facility.

One Phantom. All Tasks.

With its unique combination of a compact, easy-to-setup base phantom and highly versatile test inserts, RUBY provides you with a simple, yet comprehensive solution that helps you evaluate the entire radiotherapy treatment process.

Its scalable, modular design makes it easy for you to stay flexible and add new inserts any time. Customize Ruby to your specific needs.

Choose your insert and start testing.

RUBY Inserts

System QA

Choose the “End-to-End Test” insert for comprehensive end-to-end testing with one single insert. 

Key Features

  • MRI visibility in all commonly used sequences (T1, T2 and FLAIR at 1.5 T) – no additional components required
  • ICRU-based tissue-equivalent materials (brain, lung, bone) for enhanced CT visibility
  • Compatible with patient positioning systems and patient masks  
  • CT and MRI cavities for accurate verification of the CT/MRI image fusion algorithm of treatment planning systems
  • Point dose measurements with different detector types using the same insert

LINAC QA

Perform alignment checks of the entire system, including conventional as well as 6D couches, with the “Alignment/Isocenter Check” insert.

Key Features

  • System alignment and isocenter checks  with one single insert
  • Daily checks of IGRT positioning accuracy as recommended in  AAPM TG-179 and TG-142
  • Optional tilting base for 6D couch QA
  • Tissue-equivalent bone structures for enhanced visibility in kV and MV images
  • High-density radiopaque sphere at isocenter for easy Winston-Lutz testing
  • Automated analysis of EPID images with optional PTW  IsoCheck epid  software
  • Integrated with Track-it

Patient QA

Select the “Detector” insert for measurement-based dose verification of patient treatment plans.

Key Features

  • Fast, accurate point dose measurements with different detector types
  • “Plug and Measure” convenience using detector  holders – no need to replace phantom or exchange inserts
  • Dose verification of non-coplanar treatment plans

Use the “Film” insert for high-resolution dose distribution measurements in a plane using radiochromic films.
