KEY POINTS · The development of computed tomography was a milestone in the methodological advancement of imaging with X-rays.. · In the detector pixel invisible X-rays are converted into digital electrical impulses, which the computer uses to create images.. · Photon-counting detectors could have significant diagnostic advantages for clinical applications.. CITATION FORMAT · Schlemmer H, The Eye of the CT Scanner The story of learning to see the invisible or from the fluorescent screen to the photon-counting detector.

The goal of this study was to quantify changes in medical care during the first wave of the pandemic using radiological examinations as a comprehensive surrogate marker and to determine potential future workload.  A retrospective analysis of all radiological examinations during the first wave of the pandemic was performed. The number of examinations was compared to time-matched control periods. Furthermore, an in-depth analysis of radiological examinations attributed to various medical specialties was conducted and postponed examinations were extrapolated to calculate additional workload in the near future.  A total of 596,760 examinations were analyzed. Overall case volumes decreased by an average of 41 % during the shutdown compared to the control period. The most affected radiological modalities were sonöntgenstr 2021; DOI 10.1055/a-1368-5047. · Fleckenstein FN, Maleitzke T, Böning G et al. Decreased Medical Care Duri
