If you wish to perform an operational check of the system before using
it on a patient, or if your local or state radiation agency requires you to
perform a quality check periodically, then the following procedure may
be used for this purpose. This is only a suggested method and other
means of verifying proper operation may also be acceptable.
The following quality procedure requires a small metal object (such as
an alligator or paper clip) to be used with a Sensor and X-ray source.
1. Place the Sensor on a clean, moisture-free surface. The flat side of
the Sensor is the active area; this side should be facing up. The
side where the cable attaches to the Sensor will be facing down,
towards the table surface.
2. Place a small metal object (an alligator clip in this procedure) on
the Sensor and position the X-ray source above it by approximately
3 inches.
3. To avoid saturating the image with X-rays, set the technique
factors to values that correspond to a typically-used minimum
dosage.
4. Within your Imaging software (CDR DICOM or other imaging
program), create or open an X-ray exam and click once on any
selected target frame. Activate the X-ray source when the "Ready
to acquire image . . . Activate X-ray unit now" message appears.
NOTE: If AutoTake is enabled, the target frame should NOT be flashing RED
when ready to acquire an X-ray.
5. When the image is displayed, compare it with the samples shown
in Figure 18 on page 64. An ideal image is one with sharp edges,
clearly in focus, and having a distinct contrast between the object
and the area around it. If necessary, adjust the technique factors
and retake the image.
6. Record the results in last page of this document, or in a log book,
and / or save the exam and its image(s) for future reference.
