Method for generating digital test objects

A computer-implemented method for generating digital images encoded into a format readable by medical imaging apparatus defines, in a tridimensional continuous space, a tridimensional scene including a tridimensional continuous shape and an encompassing medium, the tridimensional shape being constituted from basic primary shapes by rotation, translation, overlapping or gathering of one or several basic primary shapes; discretizes the tridimensional scene obtained at the previous step into volume elements (voxels) using a weighting mechanism; segments the discretized tridimensional scene into voxels by creating bidimensional cross-sections of the tridimensional scene; and encodes the information describing the obtained bidimensional cross-sections of the tridimensional scene into a format readable by medical imaging apparatus.
