Abstract

The invention relates to a method for sensing ultrasound images of an object (1). The method is characterized in that an ultra-sound head (3) is moved along the object so as to sense individual image subdomains (13) of said object (1). An evaluation subdomain (14) is analyzed in order to determine the extent of the object (1) or the spacing (.delta.x) between the individual image subdomains (13). This evaluation subdomain (14) is sensed perpendicularly to the sensed image subdomains (13); that is, it represents a domain of the object (1) which overlaps at least two image subdomains (13). In this way, allocation within the individual image subdomains (13) can be determined by using the structures of the object (1) thus obtained. To this end, in particular a vertical column structure (11) of the object (1) (evaluation subdomain (14)) is analyzed, thus enabling allocation of a plurality of individual horizontal line structures (10), i.e. individual "layers" of the object (1) (image subdomains (13)) among themselves.
