Definition of Digital versus analogue imaging
Check what you remember
Read the wording for your board, then hide it and explain Digital versus analogue imaging in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
A flat panel detector produces an electrical signal that is digitised immediately, so the image is available within seconds, whereas photographic film must be chemically developed before the image can be seen.
