Diagnostic QA SolutionsThe Mercury 4.0 Phantom makes it possible to characterize advanced CT features, including Automatic Exposure Control and Iterative Reconstruction, to support protocol optimization and proper dose management for your patients.
Characterization for Effective Dose Management
The Mercury 4.0 Phantom addresses performance and effectiveness of Automatic Exposure Control / Tube Current Modulation, and evaluates image quality for Iterative Reconstruction.
TG-233 Compliance
Meet AAPM Task Group 233 requirements for performance evaluation of CT systems.
Advanced CT Metrics
Collect and analyze data for advanced CT testing recommended by AAPM Task Group 233:
- Automatic Exposure Control
- Noise Power Spectrum
- Modulation Transfer Function & Task Transfer Function
- Detectability (d')
- Cone-beam artifacts
- Superior-Inferior resolution
Optimize protocols for your advanced CT systems.
This example demonstrates checking AEC for routine abdominal/pelvis protocol, reaching a minimum of ~250 mm Water Equivalent Diameter (WED). The graph at the right demonstrates that the average of patients treated in this group have a lower WED range of ~250 mm, confirming the protocol.*

Reflecting Patient Size
5-tiered sections reflect a range of patient sizes to enable size-dependent image quality evaluation and predicting the CTDIvol for a given patient size
Case & Stand
Included stand with a handle and leveling feet makes setup easy, and wheeled case eases transport
Analysis Software
Software analysis, licensed from Duke ImQuest software, offers metrics that reflect what clinicians see
