Abstract
A method and apparatus for producing a compound ultrasound cross-sectional picture of a body, in which method a plurality of partially overlapping body scans are carried out line-wise by the pulse-echo method in one scanning plane, thereby producing image signals in digital form corresponding to the received echoes. For the real-time display of the compound cross-sectional pictures, the set of image signals produced with each scan is stored in a separate digital storage unit, at least some of the stored sets of image signals are immediately combined with one another to generate a new set of image signals corresponding to a compound real-time cross-sectional picture, and the new set of image signals is immediately fed to a television monitor in order to display the compound real-time cross-sectional picture.
