1. An ultrasound tomography device for line scanning an object to be examined from different angular directions which comprises in combination: a sagittal scanner having an ultrasound converter and being rotatably mounted so that the direction of said ultrasound converter results in a fan-like expanding transmitting/receiving direction which allows the acquisition of numerous line scan views of the object to be examined along the different ultrasound directions; translational means for moving said sagittal scanner about said object to be examined; said translational means being operative as to not interfere with said rotatability of said sagittal scanner; a time gate circuit for acquiring section by section signal data, during successive time intervals, from said ultrasound converter; and computer means for receiving said signal data and for combining said signal data in a data conversion routine for the generation of a tomography image of a coronal plane of the object to be examined.
