Test different types of Multi-Energy,
Dual-Energy and Photon-Counting CT
Protocols.
Perform System QA on DECT and PCCT
systems.
Investigate water and fat enriched
with iodine and calcium.
The phantom is designed to test different types of CT modalities 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 (? 160 mm cylinder) with 10 holes (? 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.
