The 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-adipose1. High-attenuating objects are used to test projection images, and low contrast objects simulate breast tissue for reconstructed images.
Proactive Compliance
Comply with protocols and standards, including IEC 61223-3-6 and developing AAPM Task Group 245 requirements.

Adaptable for Image Quality Tests
