Diagnostic QA SolutionsThe Modular DBT Phantom supports comprehensive testing of digital breast tomosynthesis systems.
A stack of modules supports a variety of tests and automatically aligns to the detector chest wall for easy setup and reproducibility.
Precise Tissue Mimicking
A range of simple to complex targets are precisely placed within tissue-equivalent breast material that is 50% breast-glandular and 50% breast-adipose3. High-attenuating objects are used to test projection images, and low contrast objects simulate breast tissue for reconstructed images.
Proactive Compliance
Comply with developing protocols and standards, including EUREF¹, IEC2 and AAPM Task Group 245.
Adaptable for Image Quality to MTF Tests
- Modulation Transfer Function (MTF), Line Spread Function (LSF)
- 2D & 3D Accuracy (Geometry), Artifact Evaluation
- Contrast-to-Noise Ratio (CNR)
- Edge Spread Function (ESF)
- Volume Coverage
- Missing Tissue Chest Wall
- Image Quality
Optimize the performance of your digital breast imaging systems.
The Image Quality configuration provides an overall thickness of 6.5 cm with specks, masses and fibers embedded on the central plane.
Tomosynthesis reconstructed image shows modules with objects including tungsten BBs and wires, and barium-filled grooves.
Numbered barium-filled grooves help measure missing tissue detection.
Optional breast-glandular and breast-adipose homogenous modules available
