CIRS Releases Multi-Energy CT QA Phantom
Comprehensive QA for Multi-Energy CT

February 21, 2019 (Norfolk, VA.) The CIRS Multi-Energy CT QA (MECT) phantom is designed to assure accurate performance and consistency of Multi-Energy CT scans. The phantom facilitates evaluation of scanner performance allowing users to verify the quantitative accuracy of multi-energy scans, check for artifacts in an extended field-of-view and compare the consistency and stability across different scanners. A Quality Assurance program using appropriate phantoms, is important to ensure accuracy and reproducibility for ME CT scanner performance.

The phantom features a series of 13 iodine in water & blood equivalent inserts, six calcium in water equivalent inserts and a matching kit displaying the same CT numbers at 120 kVp on a conventional CT scanner. All inserts contain a core target of Ø 10 mm inside Plastic Water® -LR for minimizing effects of “beam hardening” and can be positioned in 17 different locations within the scan field. In addition, a water vial plug that can be filled with any fluid. Adipose, Muscle and Water equivalent inserts are also provided. Inserts from the CIRS standard Electron density Phantom (model 062M/MA) can be used for extended testing due to their tissue equivalency of +/- 1% within a wide energy range.

The phantom consists of nested disks made from CIRS Plastic Water® -LR, representing both head and abdomen configurations. Two 10 cm thick sections surround a 5 cm target section for proper scattering conditions.

“Although CIRS Electron Density phantoms can be used for CT multi-energies, Model 662 is specifically designed for Multi-Energy CT.” states Vladimir Varchena, Senior Engineer CIRS

CIRS will display the Multi-Energy CT QA Phantom at ECR 2019, hall expo X1 booth 128. For more information about the Multi-Energy CT QA Phantom, visit www.cirsinc.com.
