Digital radiography was developed in the early 1960s. Frederick Weighart and James McNulty invented an apparatus that produced the first digital radiograph.
Digital Radiography is instantaneous. In less than 3 seconds you can get a very clear sharp image. Not exactly sure what "Indication for Digital radiography?" is asking, but it is higher technology and the image quality will be there forever. Its much easier to save your images in a digital format rather than film. No processing or chemicals are needed. There are so many advantages. I hope this answers whatever you were looking for.
Computed radiography uses a special plate to capture images, which are then scanned into a computer. Direct radiography captures images digitally right away using sensors, making it faster with no extra scanning step.

Analog detectors were invented prior to the advent of digital displays (circa 1922). As the technology emerged, the two were interwoven to provide digital detectors.
Can anyone plz tell me what are the advantage and disadvantage of digitaland
how we can calculate the measuring for safe distance during radiography, for 6 cury how much distance can be considered safe.
a disadvantage is that som might not have a camera to take pics with while, others do.

Digital radiography has several disadvantages, including high initial costs for equipment and software, which can be a barrier for smaller practices. Additionally, the technology requires ongoing maintenance and updates, and there may be a learning curve for staff transitioning from traditional film methods. Digital images can also be manipulated, raising concerns about the integrity of diagnostic results. Finally, the reliance on digital systems can pose risks related to data loss or cyber security threats.
Fujifilm pioneered the Computed Radiography technology in 1983, which eventually became the most common in medical diagnostic applications. Fujifilm is the worldwide market leader followed by Agfa & Carestream.
You can use it in both analog and digital circuits but it is considered as a digital device.
