No image available after exposure

Details

An exposure is performed and no image becomes available on the

NX workstation.

Cause

Due to the automatic exposure control, the dose may become

too low to trigger the DR detector.

The sensor(s) to trigger the automatic exposure detection of

the DR detector are blocked.

Solution Check both of following conditions:

Check the output of the automatic exposure on the X-ray

console. If the mAs value is low to your experience, make sure

to manually raise the mAs (keep other settings) instead of

repeating in automatic mode.

Check if no objects with a high attenuation are blocking part

of the image area.
