The Future of Computed Tomography

Modern medicine cannot be imagined without the diagnostic capabilities of computed tomography (CT). Although the past decade witnessed a tremendous increase in scan speed, volume coverage, and temporal resolution, along with a considerable reduction of radiation dose, current trends in CT aim toward more patient-centric, tailored imaging approaches that deliver diagnostic information being personalized to each individual patient. Functional CT with dual-and multienergy, as well as dynamic, perfusion imaging became clinical reality and will further prosper in the near future, and upcoming photon-counting detectors will deliver images at a heretofore unmatched spatial resolution.This article aims to provide an overview of current trends in CT imaging, taking into account the potential of photon-counting detector systems, and seeks to illustrate how the future of CT will be shaped.
