Radiography is the technical term, whereas x-ray is the layman term.

Direct digital radiography offers many advantages which include:

The concept of "direct digital" and "indirect digital" is confusing to some people.  With direct digital, the x-ray image is produced directly.  Thus, the x-ray image is shown on the computer monitor instantly. 

On the other hand, with indirect digital, the x-ray image is produced from a 2-step method: first, the pre-image is captured on a phosphor plate; second, a scanner is used to produce the final image, which is shown on a computer monitor subsequently.  The process is lengthy and cumbersome.  The quality is often compromised because of the scanning process and the quality of the scanner itself.  During scanning, the pre-image is often exposed to some amount of light, and this light degrades the image quality.  The more light exposure is, the worse the quality of the image becomes.

With direct digital, radiation exposure to the patient can be reduced because lower radiation - compared to the conventional radiography - can be used to produce a clear image. On the other hand, indirect digital actually exposes the patient to higher radiation - compared to conventional radiography. This is contrary to some advertisement.  The reason is the phosphor plate requires a slightly higher radiation dose so the x-rays can penetrate the phosphor layer on the plate's surface.  Both direct and indirect digital offer the advantage of no chemical needed for processing.  But the capital cost of direct digital is much higher.
