2.3.1.4 Floor Levelness and Flatness
The scan room floor must be leveled, and its surface must be smooth.
It is recommended that the floor in the entire scan room is leveled and flattened. If this is not
possible, it is a minimum requirement for the gantry/table installation area to be level and flat.
The floor levelness requirement is essential for proper alignment of the table and the gantry, which
affects accurate patient positioning, collimator exchange and other aspects of system functionality.
Table level may not be achievable if overall floor levelness does not conform to these specifications.
For more details, see
App.B, Measuring Floor Flatness
.
CAUTION
!
The use of floor shims is not suitable to achieve floor levelness.
Do not use fill material to compensate for holes or depressions in the floor surface.
If necessary, level and flatten the entire floor area.
