INTRAORAL IMAGING PROCEDURES
1. The orientation letter "a", printed on the PSP, may be used for reference
Note:
as you would use the dot on an intraoral X-ray film. In addition, a backwards "a"
(i.e. " "), appearing in an image, is an indication that the image has been flipped.
2. If using holders with alligator clips, it is advisable to file down the points to avoid
puncturing the Barrier Envelope. It is important to take care not to puncture the
Barrier Envelope or damage the PSP.
Take an X-ray Image
Put an image on the PSP by performing the following procedure.
1. Place the erased intraoral PSP in the sealed Barrier Envelope into the
subject's mouth exactly as you would use X-ray film. Make sure the opaque
side of the Barrier Envelope is facing the tubehead.
2. Take the exposure. The X-ray dose may typically be reduced by 80 - 85% of
that required for D-speed intraoral film (depending on X-ray system used;
the actual X-ray dose should be determined through experimentation).
3. Wearing gloves, remove the exposed PSP from the subject's mouth and
place to the side making sure the sensitive side of the barrier envelope is
facing away from any light source.
4. Repeat steps 1 through 3 as necessary to complete the subject's X-ray
series. When all necessay plates in the X-ray session have been exposed,
prepare each plate by performing the procedure below.
Preparing the Exposed Plate for Scanner Processing
1. Disinfect the Barrier Envelope (with plate still inside) and your gloves by
washing with disinfectant hand soap and water. Dry the Barrier Envelope
thoroughly.
2. Remove gloves and wash any powder from hands. Powder on a PSP will
degrade the image, and an accumulation of powder in the scanner will
lead to degradation of scanner performance.
IMPORTANT:
3. Open the Plate Transfer Box with the
lid away from you. Then, remove the
exposed PSP from its washed and dried
envelope as follows:
a. Hold the enveloped exposed PSP , with
the printed side facing up, parallel to
and about an inch above the open
Plate Transfer Box.
b. Tear the envelope lengthwise starting
at the notch to eject the PSP into the
open Transfer Box. See Figure 5.
4. Bring the Plate Transfer Box with all the exposed PSPs properly prepared
to the ScanX. The PSP is now ready to be scanned to read the image from
the PS by performing the Intraoral Imaging Procedures.
a
Be sure that the sensitive side of the PSP is facing down when it
lands inside the box (See Figure 5). If it is not sensitive side down,
TURN IT OVER IMMEDIATELY. Failure to do so may result in era-
sure of the PSP.
