Not long ago, X-ray information was recorded on film. Consequently, after development and fixation, post-processing of the image as we use today was simply only possible through another X-ray exposure with additional radiation and uncertain results. The introduction of the digital image information chain from the X-ray detector to the monitor has fundamentally changed this.
The digital transformation of radiology has been continuously expanded and improved through the application of new and increasingly powerful technical components. The omnipresence of radiological image information extends from the place of creation via PACS (Picture Archiving and Communication System) not only within the radiology department but also throughout the entire hospital and its departments, such as emergency room, operating room, wards, and outpatient clinics of the referring specialties.
Further dissemination of digital image information occurs via CD, DVD, USB sticks, and via the internet through patient and referrer portals. The end display devices of the image recipients/users can be projectors, beamers, computer screens, tablets, televisions, smartphones, or other electronic devices with suitable displays. In fact, visualizations of X-ray images on not-too-large displays like smart-phone displays or like displays of car radios are conceivable, for example, if a WhatsApp image message arrives via mobile phone to a radiologist driving a car.
Following the desires of the regulatory authorities, all these displays would have to be continuously checked for their display quality because it cannot be ruled out that an X-ray image might be displayed. Theoretically, this is conceivable. However, it is simply not feasible in our overregulated reality by now.
Fact-based arguments are discussed regarding this issue, covering various aspects of the diagnostic significance and the technical physical specifications of radiological images. Thus, we provide lawmakers and authorities with evidence-based facts to ensure that future legislative measures appropriately regulate radiologic display quality. Or even better: No need for regulations at all !?
