Accurately converting CT values to HU or electron density values plays an important role in transitioning from diagnosis to a specific treatment protocol. With the Advanced Electron Density Phantom, ICRU-44 matched tissue equivalence, automation and smart design all serve to remove uncertainties from your energy conversions.


Automated CT-to-Density Analysis
Patent-pending rod markers uniquely identify each material in a CT scan and automatically generate CT-to-density tables with capabilities in the RapidCHECK™ software. Rod markers eliminate the risk of misplaced rods, rotated phantoms, or incorrect selection of ROIs — further fool-proofing this analysis.

Sized for Wide-Beam Applications
A larger phantom body diameter supports evaluation of cone-beam CT and wide-beam CT scanners, with a removable section to support head and small body protocols.

Superior Tissue Equivalence
Phantom base and rods meet medical standards ICRU-44 and ICRP for human tissue densities, giving users additional assurance that the calculation of energy to be put into the patient is highly precise.

Compatible with Any Ion Chamber
The Advanced Electron Density Phantom is compatible with any ion chamber. Upon ordering, please specify which ion chamber you intend to use.


Highly Accurate CT-to-Density Conversion
Rods within the Advanced Electron Density Phantom mimic water, cortical bone, inner bone, and liver at a high equivalency to medical standards (ICRU-44 and ICRP) for human tissue densities, offering confidence that CT values will be optimally converted to treatment energy values.

Analysis Automation
RapidCHECK software automatically identifies the rods in the CT scan and converts the values. Software image registration further removes human errors by uncovering any discrepancies in the phantom’s position (e.g., rotated or translated head, head rotated relative to the body).

Once completed, easily export results to CSV or Excel.

TG-66 Compliance

The Advanced Electron Density Phantom supports AAPM Task Group-66 recommendations to check CT number accuracy at least monthly using 4-5 materials, and annually with an electron density phantom.

Modular Base

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

Automation

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

Investment Protection

Ensure your entire fleet of DECT systems remains statistically in control especially after service events.

Legacy Electron Density Phantom

The original CT Electron Density Phantom is available for departments in need of a basic electron density phantom.


We offer a MECT & AED CT Kit for multiuse between CT and RT teams.
