Detector coordinates are used to position the origin location which in turn defines the World 

Coordinate system.  Detector coordinates also are used to define the location of the frame data 
capture windwo which in turn defines the Frame Coordinate system. 
 

10.7.2.1  DIS - Set Manual Origin Location 

The Origin location can be set anywhere inside the :PNW? limits.  Since the Origin location 

defines world coordinates, there is no way for you to associate a particular world coordinate with 

the manual origin location.  The Origin location must be defined in terms of the detector 
coordinate system. 
See section 9 regarding the World Coordinate system and the LBA-PC online help for more 

information about Origin Locations. 
The following example describes how to enable the manual origin and set the manual origin 

location to the center of the detector.  The center of the detector in this example is at 
(112+744)/2 and (32+512)/2.

Another technique that you can use to position the origin in manual origin mode is to move the 
cursors to the desired location (:CUR) and send the :ORG command which sets the manual origin 

to the current cursor location.

The PAN command specifies the upper left corner of the capture window.  The entire capture
