RPI ID: 2016-056-401, 2016-056-603, 2016-056-601, 2017-056-602

Innovation Summary:
This portfolio features a suite of advanced filtration technologies developed to enhance the performance of dual-energy X-ray computed tomography (DECT) systems. These innovations address key limitations in spectral separation, motion artifact reduction, and computational efficiency—enabling faster, more accurate, and lower-dose imaging for both clinical and industrial applications. The technologies include novel filter configurations, dynamic beam modulation, and real-time spectral separation methods compatible with existing CT platforms.

Challenges / Opportunities:
Conventional DECT systems often struggle with balancing image quality, radiation dose, and processing speed. Limitations in spectral separation and motion artifacts can reduce diagnostic accuracy. This portfolio addresses these challenges with scalable, real-time filtration methods that improve material discrimination and reduce noise without increasing dose or hardware complexity. These solutions open opportunities in oncology, cardiovascular imaging, trauma diagnostics, and non-destructive testing.

Key Benefits / Advantages:
✔ Enhanced spectral separation and material discrimination
✔ Reduced motion artifacts and image noise
✔ Real-time imaging with minimal computational load
✔ Dose-efficient and compatible with current CT platforms
✔ Applicable across a wide range of diagnostic and industrial use cases

Applications:
• Clinical dual-energy CT imaging
• Oncology and tumor characterization
• Cardiovascular and plaque imaging
• Emergency and trauma diagnostics
• Non-destructive testing
• Spectral CT research
