IBA Dosimetry Phantoms for Quality Assurance

QA Phantoms

Integrated phantoms and test devices for your comprehensive Machine and Imaging QA needs.

Select from a range of phantoms for dedicated machine QA tasks.

  • IBA Dosimetry imaging phantoms for 2D and 3D image quality verification.

  • Integrate your existing phantoms (myQA supports most common imaging phantoms).
  • The phantoms for quality assurance are designed according to IEC/TR 60977 and DIN 6847-5 and adaptable for QA in Radiotherapy and CT simulators. The Cubic Phantom, Disk Phantom and Cylindric Phantom are ideal tools to simplify QA tasks.

Light Field Alignment Checks

  • Fast and precise check of the radiation and light fields without film or additional hardware
  • Easy setup against the light field 
  • Fluorescent plate visualizes your radiation field right after the irradiation without additional processing 
  • Field scales marked with 5 × 5, 10 × 10, 15 × 15, and 20 × 20 cm2

Cylindrical Phantom

Dose Constancy and Isocenter Check

  • Verify the mechanical stability of gantry/imager position (CBCT) with a small steel ball insert (Winston-Lutz Test)
  • Measurement of dose constancy in various gantry angles and in rotational beams
  • Use myQA Machines to check the isocenter accuracy (Winston Lutz test)
  • Adaptors available for most common ion chambers

For more information please refer to the IBA white paper ‘Tg-142_Daily Generic Tests’ and ‘Winston-Lutz & Star Shot Test’

IBA Dosimetry Disk Phantom

Disk Phantom

Isocenter Verification with Film

  • Easy and precise method of verifying isocenter accuracy (e.g. for stereotactic applications, star shot)
  • Isocenter is determined by an appendant marke
