8.5.6.4
Largest echoes
Starting from the largest echo, the system will evaluate the echoes subsequently according to size.
At maximum, as many echoes as the number of layers you have set will be evaluated (2 in the
example above). If the number of echoes detected is less than the number of layers you have set,
the system will identify less layers accordingly. This setting is of advantage if the size of all layer
interface echoes is clearly different from the size of unwanted echoes. This way, you can skip any
further complicated selection method.
8.5.6.5
Final remarks
Some of the above selection methods can only be used separately, i.e. you cannot use two or
more methods at the same time. This applies, for instance, for the settings described under 8.5.6.2
to 8.5.6.4. Overlapping or contradictory effects will therefore not occur.
On the other hand, some of the selection methods that can be usefully combined so as to
complem
ent their effects. As an example, combining “First echoes” (section 8.5.6.2) with number
of layers =2 (section 8.5.6.1) will determine both, the position and the number of echoes to be
detected.
Make sure not to combine selection methods in a contradictory kind of way that might lead to
unexpected results or results difficult to interpret. For example, it will be contradictory if you
manually select 5 echoes (section 8.5.3) because you expect 5 layer thickness values and at the
same time, adjust the number of layers to 2 (section 8.5.6.1). As a consequence of such setting,
only 2 thickness values would appear instead of 2.
