Optimization-based phase retrieval for material decomposition with multi-energy computed tomography
Giavanna Jadick, Patrick La Rivière
Multi-energy CT has long demonstrated its ability to enhance image quality with material decomposition. Yet, it has largely been limited to applications that already have high cont…

Accuracy of propagation-based phase-contrast CT under the projection approximation
Giavanna Jadick, Patrick La Rivière
X-ray phase-contrast imaging has the potential to improve image contrast with lower dose by probing an object's refractive properties as well as its absorptive properties. To recon…
