1 Preparing for Calibration
1.1 Recommended Panel
Configurations
Prior to starting panel calibration it, is
recommended that basic device configuration is
setup properly in the ViZion DR+ acquire
software.
Refer to the appendix in the technician folder
for specific configuration details.
1.2 Powering on the Panel
Before you power on the panel, allow the panel
to acclimate to room temperature if the panel is
brought in from the cold or heat or if room
environmental controls have been changed.
1. Turn panel over and position it so that
battery connector pins, located in the
top left of the battery compartment, are
pointed toward you.
Figure 1: Panel Positioning for Inserting Battery
2. Slide a fully charged battery into the
battery compartment, aligning the arrow
on the battery with the connector pins.

4. Once battery has been inserted, panel
detector automatically activates the
Power On Sequence and should be
available for use within 90 seconds.
If panel does not power on
automatically, press power button on the
side of the panel, holding it in for 5
seconds and releasing.

3 Calibrating ViZion DR+
3.1 Environment Setup
1. Align the panel with the X-ray tube.
2. Set tube head Source to Image-receptor
Distance (SID) to 60”.
3. Open the collimator to allow full
coverage of the surface of the panel.
The collimator light should extend an
inch beyond the edges of the panel.
4. Remove any anti-static grid or grid-cap.
Make sure panel is out of bucky and no
objects are between the panel and tube
head.
5. Configure 70 kV 5.4 mAs on the X-ray
control console.
3.2 Performing Panel Gain
Calibration
If using an integrated generator, it must be
configured to make exposures in Direct Mode to
run calibration. Use the manufacturer software
parallel to iDemo to control the generator
settings, or adjust kV and mAs from the
generator console.
1. In the Correction section, configure the
following setting.
Offset = POST

2. Click Create.
3. Select the Gain tab.
Figure 14: Gain Settings
4. Set the Expected Gray Value field to
6000 (Figure 14).
5. Click New Gain Point (Figure 14).
6. Click PREP and make an exposure
during the “Exposure Enable” status (the
current status displays at the bottom of
the screen). While the image is
transferring, the status changes from
“Image Getting” showing the panel has
triggered an image, to “Exposure
prohibit (post offset)”, to “Exposure
enable (post offset)”.
Figure 15: Image Transfer Status
7. After image transfer completes and the
status “Got Image” is displayed, verify
that the Center Average value is
between 5900-6100.
Figure 16: Verifying Center Average
•If the value is below 5900,
increase the dose.
•If the value is above 6100,
decrease the dose.
8. After dose adjustments are made,
repeat Steps 5 - 7 until the center
average value is between 5900-6100.

expected range of 5900-6100, click
Select (Figure 17) to add that value to
the Selected Points list (Figure 18).

of 5 gain frame values in the Selected
Points list.

3.3 Performing Panel Defect
Calibration
NOTE: This step is optional. After
performing a Gain Calibration, continue by
performing a Defect Calibration (only
necessary if dead pixels and/or dead pixel
lines are present in acquired images). A
new defect map applies these corrections to
mask out dead pixels when possible.
1. In the Correction section, configure the
following setting.
Offset = NO
2. Click Create.
Figure 21: Correction Settings
3. Select the Defect tab. The Current
Frame # defaults to “1”. A total of 19
frames must be acquired to complete a
full defect mapping.
Figure 22: Defect Calibration
4. Configure the dose as close to the
requested kV as possible, trying to
adjust mAs to get within ±100 of the
expected gray value (some deviation of
kV may be required).
The suggested mAs values to use for
each frame are in parenthesis below.
Adjust mAs up or down as needed.
Frame 1: 70kV / expected gray value =
1000 (0.6 mAs)
Frame 2: 40kV / expected gray value =
1000 (5.1 mAs)
Frame 3: 100kV / expected gray value =
4000 (1.2 mAs)
Frames 4-19: 70kV / expected gray
value = 11000 (10.5 mAs)
5. Click Start Creating. A message
displays providing the amount of kV to
use for that frame #. The message also
provides the expected gray value for
that frame #.

6. Click OK after you have read the
expected dose information message. A
message in red letters “Waiting for
PREP …” displays.
7. Set your kV and mAs accordingly.
8. Click PREP and make an exposure
during the “Exposure Enable” status.
Figure 24: Calibration Status
While waiting on the image to transfer,
the status changes from “Image
Getting”, indicating that the panel has
triggered an image, to “Exposure
prohibit (post offset)”, to “Exposure
enable (post offset)”.
9. After image transfer completes and the
status “Got Image” is displayed, review
the last line and look for the Center
value, verifying that the value is within
±100 of the expected gray value for that
frame #.
If the value is more than 100 below or
more than 100 above the expected gray
value, adjust your mAs up or down.
NOTE: If the Center value returned is
too low or too high, the counter may still
advance to the next number and a pop-
up for the next frame may display.
Be sure to click OK and select the
dropdown next to “Current” and reset
the Current frame # back to the previous
# that needs to be reacquired.
Example: In the following example
(Figure 25), the returned center value
for “Current 1” is 700, which is too low
because it is not within ±100 of the
expected center value 1000.
Also notice that the counter increased to
the next frame #. Therefore, before
acquiring the next frame, go back to
frame 1, and re-acquire frame 1, after
increasing mAs.
•Click OK and select dropdown
next to Current and select “1”.
•Then repeat steps 5-9 until the
returned value is within ± 100 of
the expected gray value.
