11.12.4 Gain Calibration Steps
The general procedure for gain calibration for all modes is described in
Table 13
.

Gain Calibration Sequence in ViVA- All Modes
Action
Results
Power On
Power On the detector by inserting a battery. Once the detector is
powered on the detector is in low-power state. Wait 5 minutes prior to
gain calibration.
Offset Calibration
Software performs a new Offset calibration referred to as dark field
acquisition.
Note:
X-rays must not be used for this part of the calibration.
Gain Calibration
Multiple Gain frames taken. Software pauses at each frame so that the
operator can apply X-ray exposure.
Note:
The exposure should ideally be at a level and technique
representative of the typical exposure dose for the
detector
during procedures.
Repeat
The above procedure must be repeated for each of the stored imaging
modes.
1
Choose the
desired imaging mode
from the Mode Drop Down Menu.

2
Under the Acquisition menu, click
Gain Calibration
. This invokes
hardware handshaking
for the dark field calibration.
