Multi-Energy QA Phantom

For testing different types of Multi-Energy, Dual-Energy and Photon-Counting CT Protocols

  • For different types of CT systems with dual-energy, multi-energy or photon-counting setups
  • Test multi-energy spectral CT protocols and post-processing techniques
  • Decompose Iodine and CaHA levels

The phantom is designed to test different types of CT systems with dual-energy, multi-energy or photon counting setups. Image acquisition and image processing at multiple energy levels is improving visualization for computed tomography. The QRM Multi-Energy QA phantom is ideally suited to test multi-energy spectral CT protocols and post-processing techniques. 

The phantom consists of a removable/stand-alone head phantom (Ø 160 mm cylinder) with 10 holes (Ø 25 mm) to house different inserts and an oval (QRM-10150) or an optional circular (QRM-10151) body, equipped with 9 bores. Body and Head section are made of water-equivalent material (CTwater).

The phantom is equipped with a set of 26 inserts including rods enriched with several contrast media (water+iodine, adipose+iodine) as well as calcium (water+calcium hydroxyapatite), each material with different concentrations. Additionally, water- and soft tissue-equivalent inserts (adipose, liver, brain - ICRU Report 44 and 46) are included. Mass density, concentration and electron density are provided for all materials.

Other materials (e.g. blood+Iodine, various ICRU-tissues etc.) can be manufactured upon request.

Optionally, all inserts (recommended for/especially the higher attenuating materials) can be manufactured with reduced material diameter (e.g. Ø 10 mm) embedded in a water-equivalent shell (in total Ø 25 mm).
