Multi-Energy QA Phantom

Unmatched precision and robust reliability for excellence in multi-energy CT QA

Trusted by top-tier radiology teams, pioneering research institutions and global imaging leaders, it streamlines calibration and performance validation — ensuring consistent, accurate results across clinical practice and advanced research.

Key Advantages

Photon Counting CT

It is designed to test different types of CT systems with dual-energy, multi-energy or photon counting setups. All materials tested on NAEOTOM Alpha.

Iodine / CaHA Levels

It is equipped with a set of 26 inserts including rods enriched with several contrast media as well as CaHA.

AutoQA Plus Software

Once the phantom is accurately positioned at the isocenter and scanned using optimized protocols, IQ parameters are automatically assessed.

Compliance & Standards

The phantom is fully AAPM TG-299 compliant, making it suitable for establishing robust QA programs in hospitals and research institutions.

Application Benefits

Removable/stand-alone head phantom

The phantom features a detachable / standalone cylindrical head phantom (Ø 160 mm), designed with 10 holes (Ø 25 mm) to house various inserts. In addition, it includes an oval-shaped body offering 9 holes. An optional circular body (QRM-10151) with 9 holes is also available.

Includes 26 inserts

A set with a total of 26 inserts is provided for the measurements. The set consists of three water-equivalent inserts and one ICRU Adipose, liver and brain insert each.

For spectral measurements, six inserts with iodine concentrations from 0.5 to 15 mg/ml (water-equivalent base material), six inserts with iodine concentrations from 0.5 to 15 mg/ml (adipose-equivalent base material), five inserts with CaHA (calcium-hydroxyapatite) concentrations from 25 to 400 mg/ml (water-equivalent base material), two inserts with iron with 5 and 10 mg/ml (liver-equivalent base material), and a fillable insert for distilled water or other liquids are available.

Mass density, concentration and electron density are provided for all materials.

Additionally, inserts with other contrast media (e.g. gadolinium), various ICRU Tissues, metals and additional water-equivalent inserts can be ordered optionally.

Analysing Software

>AutoQA Plus automated image quality software

AutoQA Plus is an automated image quality software designed to provide repeatability and accuracy by reducing operator error during image quality tests of various spectral CT technologies from different manufacturers performed with the QRM Multi-Energy QA Phantom.

Applications

Applications

Multi-energy CT post-processing and material decomposition.

Investigate water and fat enriched with iodine and calcium.

Water-Equivalent Phantom for Photon Counting CT

Automated QA with AutoQA Plus

Enhance repeatability and reduce operator error using AutoQA Plus, an automated CT QA software that evaluates image quality parameters with precision.

The software detects the inserts with different concentrations and materials and places of the VOI (Volume of Interest)
The mean VOI (Volume of Interest) and the measured SD (Standard Deviation) of the CT numbers are measured and displayed on the “Trend Report Links”

MEP - Set of 6 Gadolinium rods, QRM-10152

Multiple contrast studies

Optional inserts containing Gadolinium (Gd) are available for advanced K-edge imaging applications.

The CTwater + Gadolinium set (QRM-10152) includes six concentrations: 0.0, 1.0, 2.0, 5.0, 10.0 and 15.0 mg/cm³

Extension Rings and Expansion Set

Beyond the extension rings used to simulate obesity, two supplementary extension blocks are optionally available. These are particularly valuable for wide detector coverages and offer insights into the influence of scattered radiation on image quality, material mapping and VMI performance.
