QRM -Multi-Energy QA Phantom for CT Protocol Testing
The Multi-Energy QA Phantom from QRM is specifically designed for testing CT systems employing dual-energy, multi-energy, or photon-counting methodologies. This phantom is pivotal for optimizing image acquisition and processing across multiple energy levels, thereby enhancing the visualization capabilities in computed tomography (CT). The phantom features a removable head (160 mm diameter) with ten holes for various inserts and a body available in either oval or circular configurations. Both the head and body are made from CTwater, a water-equivalent material. It includes a set of 26 inserts containing different contrast media like iodine and calcium hydroxyapatite, each at varying concentrations, alongside soft tissue-equivalent materials such as those mimicking adipose, liver, and brain tissues based on ICRU Reports 44 and 46. Optional configurations include inserts with reduced material diameter embedded in a water-equivalent shell. Technical specifications include measurements for physical density, concentration, and electron density relative to water with an accuracy of ±5 HU from specified values.
- 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).
