Picture element - in a digital radiograph each assigned a shade of gray
based on xray transmission pattern from that specific area
What do under exposed images look like on digital radiographs?

More blurry than white. The digital system can compensate much more
than analogue but still has points where soft tissue becomes hard to see.
EXPOSURE LATITUDE DOES MATTER - noise, and harder to identify than
a mess up on analog
, What is the process of image formation in direct digital xray?

- Xray beams directly strike the photoconductor typically made of
amorphous selenium which readily absorbs xrays. Electrons are liberated in
the selenium by the charge and are converted to a digital image.
What does DICOM stand for?

To convert to digital images - must you purchase a new x-ray machine?
Give this one a try later!
No. You can use the same x-ray tube, x-ray table, and grid. Unless you are
using a charge coupled device which has the digital hardware stored inside
the x-ray tube.
Bit depth is what?
