5 Preliminary procedures
This chapter describes the procedures to perform compulsorily before starting scanning patients.
These procedures are three:
• X-Ray source conditioning;
• Daily check;
• Blank acquisition;
This chapter describes also some required and/or useful functions:
• Beam limiter test
