Creation of a new pixel map (if necessary)
0
During the calibration function, you have the option of creating a new pixel map of the
detector. The pixel map indicates which pixels in the detector‘s array might not be reading
X-ray densities correctly and therefore should be ignored when the image is acquired.
This is similar to a bad spot map for a computer‘s hard disk.
A new pixel map should be created when an excessive amount of pixel dropout is occur-
ring repeatedly on images displayed in the image Preview window.
To create a new pixel map:
1. Start the service software from the syngo menu bar:
Options -> Service -> Local Service
NOTE
The Service Level 5 or higher is necessary to do the bad pixel map-
ping.
2. Select
Acquisition System.
