These results demonstrate that optimal filtration strategies for PCCT are material dependent, and provide guidance for filter selection at PCCT MD applications, particularly those involving tantalum contrast agents, dual-contrast protocols pairing low and high-Z materials, or high-energy virtual monoenergetic image rec...
The results demonstrate that the proposed CBC design offers a significant sensitivity advantage, making it highly suitable for high-performance, small-volume clinical applications such as brain and cardiac molecular imaging.
Electron density provides a significantly better CNR for liver metastases with electron density derived from dual-energy computed tomography compared with both conventional and VMI at 40 keV reconstructions, in both the unenhanced and portal-dominant phases.
The proposed framework improves dose prediction while incorporating physically meaningful priors into the learning process, offering a promising basis for PET-based dose-monitoring model development in CIRT.
While sharper kernels and lower monoenergetic bins increased noise and reduced CNRD, they significantly improved spatial resolution, achieving sub-millimeter feature detectability in one patient, supporting feasible lesion detectability under these thresholds.
