Computed Tomography (CT)

Computed tomography (CT) systems use a series of X-ray images to create an image volume dataset with slices that can be manipulated on any plane using advanced visualization software. The section includes computed tomography scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (dual-source CT), and iterative reconstruction dose reduction software.

Design of the human-scale dark-field CT system. (A) Layout of the Talbot–Lau interferometer integrated into a conventional medical CT system. Bent gratings in an inverse geometry allow positioning of G0 and G1 close to the source. A large G2 is positioned close to the detector. Contrast formation is illustrated in SI Appendix, Fig. S1. (B) CT gantry equipped with a Talbot–Lau interferometer. The large G2 covering the detector is visible, while the G0 and G1 fixture is concealed by the collimator box. A huma
