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.
Spectral computed tomography (CT) has become an important extension of contrast-enhanced CT (CECT) in oncologic imaging by providing material-specific information beyond conventional morphologic assessment. Dual-energy CT (DECT), implemented on energy-integrating detector CT (EID-CT) platforms, has demonstrated the val...

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.
Thallium bromide is a suitable material for medical imaging, providing enhanced diagnostic accuracy and potential dose reduction compared to CdTe and CZT, and consistently has superior performance.

This study demonstrates the feasibility of DE CBCT technology on the HyperSight imaging system through a novel statistical material specific imaging algorithm and VMI-based CNR improvements and metal artifact reduction.
Purpose
Ultrasound computer tomography (UCT) is a promising medical imaging method for various applications such as the breast and brain. Current UCT image reconstruction methods fall broadly into two categories: time-of-flight (TOF)-based ray-tracing methods and full-waveform inversion (FWI) methods. Ray tracing metho...
