ABSTRACT:
In an exemplary embodiment partial images of an object are obtained by scanning the object from different directions, e.g. by compound scanning. For a given object region or point, the different partial images may include a response maximum signifying a directionally reflecting region. Other object regions may provide echo signal amplitudes in a range signifying a locally isotropic scattering. According to the disclosure, the partial images are linked or combined taking account of the nature of the respective object regions as being directionally reflecting or nondirectionally scattering.
