5   Preliminary procedures

5.3  Blank acquisition

During  

Blank   acquisition

  a   background   image   is   acquired   in   order   to   verify   and   calibrate   the   detector

performances.

This procedure is automatically performed by the software every two weeks.

The resulting blank acquisition image should look like shown in the figure. 

Please carefully verify that no artifacts or objects appear.

WARNING:

Before   launching   the   procedure,   please   verify  that   the
scan area is completely free from objects. To that end, if
not done previously, take out the patient table
