projection. We will present solutions for the external lateral projection. For such a
projection, the appropriate set of foot bone names was adopted:

• tibia (t),

• fibula (f),

• talus (ta),

• heel (c),

• os naviculare (on),

• os cuboideum (oc),

• os cuneiforme intermedium (oci),

os cuneiforme tertium (oci).
A linguistic description was also introduced to present the foot bone skeleton (Fig. 2)
corresponding to the correct anatomy of this part of the lower extremity.

In order to analyse X-rays of foot bones in the external lateral projection, it was
obligatory to define a graph representation of these bones showing numbers consistent
with the neighbourhood relationships of these structures. Such a definition is
formulated based on a description of a graph of special topological relationships
between particular elements of the graph. A graph of spatial relationships is show
in Fig. 3:
Using a graph of spatial relationships to build a graph containing the numbers of
adjacent foot bones for an external lateral projection is shown in Fig. 4.
The next stage in conducting a substantively correct cognitive analysis is to
define the appropriate formalism for the linguistic analysis and interpretation of
