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.
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.
'Direct' radiography implies that the other form is 'indirect' radiography which is indeed the implicit connotation. With digital radiography the results of the X-ray are immediate as the system is connected directly to the computer. In indirect radiography (also called computed radiography) a phosphor plate is used, become radiated, and then are scanned following this exposure to see that X-ray's outcome.

In 1905, Dr. howard Rober and A. Cieszyski who was an engineer discovered the bisecting technique.

Computed tomography and digital radiography are both computer-assisted x-ray technologies.
The difference between digital x ray and standard x ray is much like the difference between digital and film photos. Digital radiography bypasses the chemical processing and through digital technology, one is able to enhance images and transfer images electronically.
I discovered one in a drawer just a couple of days ago!The digital camera was not discovered; it is the result of many years of invention and product development.
