Workflow Step

Dual-energy CT imaging delivers quantitative results that demand regular quality control. Single energy QC programs are simply inadequate for dual-energy CT. The Multi-Energy CT Phantom provides the rigor needed to ensure optimal system performance.

Automated Material Discrimination
Easily test material discrimination using solid rods representing iodine, calcium, blood, adipose, and more. Patented rod markers enable automated analysis to streamline this process.

Ensure Scanner Efficacy & Consistency
Test the efficacy of your clinical protocols for multi-energy analysis and compare consistency and stability across different scanners.

Comprehensive Testing of Scanner Performance
The Multi-Energy CT Phantom enables robust evaluation of scanner performance, including:

  • Material discrimination testing using solid rods representing iodine, calcium, blood, adipose, and more
  • Ensuring efficacy of clinical protocols for multi-energy analysis
  • Verifying quantitative accuracy of multi-energy scans
  • Comparing consistency and stability across different scanners
  • Checking for artifacts in an extended field-of-view
  • Testing in head (20 cm) and body (40cm x 30 cm) configurations
  • Automating analysis with patent-pending rod marker technology

Optimize your dual-energy CT system.

Extended Field-of-View Evaluation

The 40 cm extended field size enables checking for artifacts in a larger phantom on a weekly or monthly basis, as recommended by the ACR Quality Control Manual.

Modular Base

The Solid Water® HE base is compatible with two sets of rods for double duty as multi-energy CT QA as well as TPS calibration.


Patented rods include unique markers for quick identification during a CT scan, and enable automated table completion.

Investment Protection Features

Self-aligning rods deter potential breakage and an adjustable stand makes setup simple and precise. A wheeled case is included for easy transport.

Reinforce the capabilities of your dual-energy CT system.
