Note:
1. The orientation letter “
a
”, printed on the PSP, may be used for reference 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 patient'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 patient'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 patient's X-ray series. When all necessary
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:
Be sure that the sensitive side of the PSP is facing down when it lands on the PSP Transfer
box (See Figure 8, View C). If it is not sensitive side down, TURN IT OVER IMMEDIATELY.
Failure to do so may result in erasure of the PSP.
3. Lay the PSP Transfer box on a flat surface near the ScanX as shown by Figure 8, View A.
4. As shown by Figure 8, View B, 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 PSP Transfer box.
b. Tear the envelope lengthwise starting at the notch to eject the PSP onto the PSP Transfer box.
5. As shown by Figure 8, View C, the PSP is now ready to be scanned to read the image from the PSP
by performing the Intraoral Imaging Procedures.
