Step 4: execute the digital tomosynthesis exposure sequence

1. In the digital tomosynthesis screen of the software console, click the
button to start the digital tomosynthesis workflow.
If the X-ray system position is not suitable to perform the examination, the
button is disabled. Try adjusting the X-ray system to enable the button.
During the tomosynthesis workflow, restrict operation to the prescribed
steps. In particular, do not use the remote control and do not adjust the
table height.
2. Press and hold down the automatic positioning button.
The X-ray tube is moved to the start position of the digital tomosynthesis
exposure. The ready for exposure status is indicated.
3. Press and hold down the exposure button to make a digital tomosynthesis
acquisition sequence.
Hold the exposure button pressed until three beeps are heard to indicate
that the examination has finished.
Together with the auditory signal, messages are displayed on the software
console to indicate that the examination has finished.
When the exposure button is released before the movement has finished,
the exposure sequence is aborted and the reconstruction may fail.
The acquisition sequence is stored and displayed as an acquisition
sequence thumbnail in the lower half of the Image Overview pane.
The last image of the sequence is visible in the thumbnail. An acquisition
sequence thumbnail is indicated with a white Play icon in the center.

The image processing to create the reconstruction sequence is started
automatically and may take at least a minute.
WARNING:
No reconstruction is possible if the exposure button is
released too early.
WARNING:
Image transmission may be interrupted if the DR detector is
reset or moved away from the system. Do not use the DR
detector until the thumbnail of the acquisition sequence
becomes visible.
