5 Introduction to imaging plate
technique
5.1 Imaging plate
Imaging plate is a film-like thin, flexible and wireless
phosphorescent plate, which works as a wireless receptor.
Imaging plate is better than film because:
• no need for film development chemicals and dark-
room.
• tolerates wider range of exposure values, both
overexposure and underexposure are practically
eliminated.
• All benefits of digital images.
Imaging plate sizes:
■ 0 child
■ 1 small adult
■ 2 large adult
■ 3 bitewing
■ 4C comfort occlusion
The support base material is black plastic. On top of the
base material is blueish photo-stimulable layer (does not
contain any prosphor/phosphorus). On top of the blueish
material is a top coat protective layer and the edges are
closed with lacquer.
The phosphorescent side of the plate records and stores
the image. This side is sensitive and should be protected
against dust and dirt.
Visible light clears the image information from the plate, so
it must be protected from ambient light between exposure
and processing.
Even when packed properly, the image starts to fade out
slightly within time.
Sensitive side
1. Protective (topcoat) layer
2. Photo-stimulable layer
3. Support material layer
