Dual-Energy Phase-Contrast Computed Tomography to Improve Material Discrimination
Kadri Aditya Mohan | 22-ERD-011
We will develop a new mode of three-dimensional imaging called dual-energy x-ray phase-contrast computed tomography that will enable high-contrast, quantitatively-accurate characterization of low x-ray absorption contrast materials, which are currently difficult to measure. This new imaging capability will use in-house, lab-based x-ray sources to enable advanced, in-situ characterization in support of national security missions.
