IMAGING PLATE (IP)
8.1 GENERAL INFORMATION CONCERNING IPS
WARNING:
Risk of poisoning. IPs are not intended to come into direct contact with the patient mouth. Always place
them in a hygiene bag prior to positioning them in the patient’s mouth. If the patient swallows all or
part of the IP, immediately remove it from the patient’s mouth. The patient must seek specialist medical
assistance specialist as soon as possible. If a patient bites and damages the hygiene bag, thoroughly rinse
out his/her mouth.
• An IP is a fl exible intra-oral X-ray image receptor. It is made up of a layer of small photo-stimulable
phosphorus particles uniformly coated onto a polyester support fi lm and shielded with a top coat protective
layer.
Phosphorus
We do not use phosphorus or phosphorous-based materials for our IPs. We use phosphorescent particles.
These phosphorescent particles are sealed between the upper protective layer and the polyester support
fi lm. When used normally, these particles cannot become detached from the other parts of the IP.
The phosphorescent particles in the IP are excited by X-rays and store this energy in the form of a latent
image. When the IP is scanned by the PSPIX system, this latent image is stimulated by a laser, activated and
then converted into a digital image. The IP is then exposed to light so it can be erased and immediately
reused.
• The IP has 2 sides:
- The blue side of the IP is the side that “records” the X-ray image. This is the ACTIVE side.
The letter “P” is printed on the active side of the IPs and it is therefore visible on the X-ray image. It serves
as a reference point for the dentist when he/she is placing the IP in the patient’s mouth, and facilitates
orientation of the X-ray image during diagnosis.
Note that the same reference point is marked on the protective cover. The two reference points must be
superimposed over each other when the IP is placed in the protective cover.
- The black side is the inactive side. It is marked with the ACTEON logo, the size and the IP serial number.
