TL;DR: The results indicate that the proposed system will deliver volumetric images of the extremities with soft-tissue contrast resolution comparable to diagnostic CT and improved spatial resolution at potentially reduced dose.

TL;DR: Intraoperative CBCT using a high-performance mobile C-arm prototype demonstrates image quality suitable to guidance of spine surgery, with task-specific protocols providing an important basis for minimizing radiation dose, while maintaining image quality sufficient for surgical guidance.

TL;DR: A fast MC simulator combining GPU acceleration with variance reduction provided a systematic examination of a range of CBCT configurations in relation to scatter, highlighting the magnitude and spatial uniformity of individual scatter components, illustrating tradeoffs in CNR and artifacts and identifying the system geometries for which grids are more beneficial.

TL;DR: An image registration and visualization system for decision support in spine surgery by automatically labeling vertebral levels in fluoroscopy using a GPU-accelerated, intensity-based 3D-2D registration, applicable beyond the specific case of vertebral labeling.

TL;DR: A fairly comprehensive framework for artifact correction to enable soft-tissue brain imaging with FPD CBCT is presented and the resulting image quality motivates further development and translation of the FPD-CBCT system for imaging of acute TBI.
