RUBY Modular QA Phantoms

Base phantom or head phantom. Multiple inserts. System QA. Linac QA. Patient QA.

System QA

Choose the “System QA” 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 verification of dose calculations at different tissue densities
  • 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 “Linac QA” 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
  • Ceramic MV visible 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.

Farmer Ionization Chamber 30013 waterproof

Farmer® Ionization Chamber waterproof, Type 30013

Farmer® Ionization Chamber 30013 waterproof

Waterproof therapy chamber for reference dosimetry in high-energy photon, electron and proton beams

  • Acrylic wall, graphited
  • Aluminum central electrode
  • Waterproof
  • Sensitive volume 0.6 cm3, vented
  • Reference class in accordance with IEC 60731 and AAPM TG-51 Addendum

The 30013 Farmer chamber is the standard ionization chamber for reference dose measurements in radiation therapy.

Correction factors needed to determine absorbed dose to water or air kerma are published in the pertinent dosimetry protocols.

Its waterproof design allows the chamber to be used in water or solid state phantoms. The acrylic chamber wall ensures the ruggedness of the chamber.

Semiflex 3D Ion Chamber 31021

  • Vented, waterproof, fully guarded – the ideal chamber for relative and reference dosimetry measurements in water, air or solid state phantoms
  • True 3D geometry – uniform response in any direction
  • Unique design – fast, accurate scanning in in-plane and cross-plane directions without tank rotation or change of detector setup
  • Easy horizontal or vertical mounting for high-resolution measurements in both radial and axial orientations
  • Reference-class ionization chamber with exceptional dosimetric characteristics – suitable for reference dosimetry following standard dosimetry protocols, e.g., IAEA TRS-398, AAPM TG-51
  • Small size (0.07 cm³), high spatial resolution – perfect for measurements in small and FFF fields down to a field size of 2.5 cm x 2.5 cm
  • Radioactive check device optionally available
Suitable for photon and electron dosimetry in multiple applications
 
  • LINAC Acceptance Testing

The New Reference Class

Semiflex 3D meets and exceeds the performance requirements of a reference-class ionization chamber as laid out in AAPM TG-51 and IEC 60731:

  • Minimal polarity effect (< 0.4 % correction, < 0.5 % maximum variation)
  • Extremely low volume effect (est. ≤ 0.05 % correction in FFF field)
  • Excellent chamber settling (< 0.3 %)
  • Very low post-irradiation leakage – far below IEC 60731 requirements
  • Significantly reduced cable effects (< 200 fC / (Gy * cm))
  • Minimal chamber-to-chamber variation – reliable kQ and kS values
