Diagnostic Data
The first 40 pixels of each image contains data that pertains to the image and the detector. It is
possible to monitor certain internal voltages, internal temperatures, firmware version, and frame
count. The frame counter is a free running counter that increments with every frame start.
The diagnostic data also contains the data from three temperature sensors to monitor the
temperature of the a-Si sensor. The maximum value of any temperature sensor during normal
operation should be 55°C to prolong the life of the sensor.
ViVA software freezes
Restart the computer and re-launch the ViVA software.

Detector dropped
1. Remove the cables from detector and inspect for damage.
2. Re-attach the cables to the detector and see if it powers on.
3. Re-establish a link.
4. Acquire an image from the detector and inspect for regions of
missing data.
Note:
If the detector has been dropped and is not returned to
Varex, a new gain calibration must be performed.
