Neural-network-based material identification in photon-counting computed tomography using region-of-interest spectral features

A. Miadzvetski, V. Rozhkov, R. Sotenskii +2

The paper explores using neural networks to identify materials in photon‑counting computed tomography by analyzing spectral features extracted from regions of interest in reconstru…
