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. Patent-pending 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.


Patent-pending 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.
