Abstract A method of and apparatus for producing an ultrasound cross-sectional picture of a body, in which method at least two different and partially overlapping sector scans of the body are carried out by the pulse-echo method, in one scanning plane and with an ultrasound transducer unit comprising a single transducer. In order to produce a real-time display of a relatively large scanned area, the transducer unit com- prises a transducer (12) which is pivotable about an axis of oscillation (13) perpendicular to the scanning plane, performs an oscillatory movement about the axis of oscil- lation and between two end positions on each scan, forms a rigid unit, and is segmented into adjacent transducer ele- ments. In performing the scans, at least two different transducer elements or two different groups of adjacent transducer elements of the transducer (12) are used, each transducer element or each group of transducer elements 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 (13) remains unchanged with respect to the body (11). (Fig. 1)
