11.  TOMOGRAPHY 

 
This section will occasionally use procedures described in previous sections.  

Please refer to those sections when needed. 

This procedure will produce tomographic images. 
To do this use the chin rest support and head support.  
 

 

Chin rest for tomography exposure 

  
 

11.1. 

GETTING THE SOFTWARE READY 

 

Open the Imaging software and make sure the green light is on before start. 

 

 
Press
