ABSTRACT:
A real-time method and appartus is disclosed for scanning large body areas to produce an ultrasound cross-sectional picture of the area in which at least two different and partially overlapping sector scans of the body are carried out in one scanning plane by the pulse-echo method utilizing an ultrasound transducer unit having a rigid transducer which is pivotable about an axis of oscillation perpendicular to the scanning plane, which performs an oscillatory movement about the axis of oscillation and between two end positions on each scan, and which is segmented into adjacent transducer elements. In performing the scans, at least two different transducer sets are used, each containing one or more transducer elements, each transducer set being used both for the emission of the ultrasound pulses and for the reception of echo waves. In all the scans the position of the axis of oscillation remains unchanged with respect to the body.
