Sun Nuclear Multi-Energy CT Phantom
Comprehensive Testing, Tissue Equivalence • Features 28 inserts representing different dimensions and concentrations of iodine, calcium, blood, adipose and other materials of particular interest to Multi-Energy CT (MECT) • Enables comprehensive tests of Multi-Energy CT scanner performance • Expanded range of HE Iodine and HE Calcium Multi-Energy CT scanners have enabled improved clinical differentiations, such as distinguishing blood from calcification and calcification from iodinated contrast.1,2 They can also create virtual mono-energetic images for clinical evaluation. However, the ability to achieve these benefits depends not only on one¡¯s equipment, but on the protocols used. Sun Nuclear¡¯s Multi-Energy CT Phantom enables robust evaluation of scanner performance. • Test material discrimination using solid rods representing iodine, calcium, blood, adipose, and more • Ensure the efficacy of clinical protocols for multi energy analysis • Verify the quantitative accuracy of multi-energy scans • Compare the consistency and stability across different scanners • Check for artifacts in an extended field-of-view • Test in both head (20 cm) and body (40cm x 30 cm) configurations • Enable automated analysis with patented rod marker technology Ensure Accuracy Scanner accuracy can vary based upon scanner hardware, the dual energy post-processing, and the mAs used. Without an appropriate phantom, neither scanner accuracy nor variability are well known. Use of our calibrated high-Z inserts enables such quantification. Additionally, protocols that appropriately balance patient dose with system performance can be identified. Automated analysis The Multi-Energy CT Phantom supports automated analysis using patented rod marker technology. Each insert is tagged with a pattern, making it uniquely identifiable in a CT scan. Upcoming software will leverage these identifiers to evaluate results quickly and with minimal user interaction. Enhance confidence in your virtual mono-energetic images Monochromatic HU numbers have been shown to vary between scanners.3 Moreover, the performance of multi-energy algorithms can be compromised by insufficient mAs. By utilizing Tissue Mimicking Material that replicates expected HU dependencies from 40-200 keV, the Multi-Energy CT Phantom lets you quantify these effects and define effective operating parameters. Evaluate an extended field-of-view The ACR Quality Control Manual recommends checking for artifacts in a larger phantom on a weekly or monthly basis. The 40 cm extended field size of the Multi-Energy CT Phantom enables this artifact check to be performed concurrently with other evaluations, efficiently fitting into your workflow |
