Abstract

The invention relates to a method or a device for recording ultrasonic images of an object (1) in which ultrasonic waves are radiated onto the object (1) by an ultrasonic emitter, and ultrasonic waves reflected by the object (1) are received by an ultrasonic receiver. For recording individual image partial areas (6), the ultrasonic emitter or ultrasonic receiver (18) is displaced along the object (1) or is at least partially rotated with regard to the object (1). The corresponding movement (S) of the ultrasonic transmitter or of the ultrasonic receiver (4, 18) is progressively detected by a detector (9, 23) and is assigned to the individual image partial areas (6). As a result, it is possible to record the object (1) by manually moving the ultrasonic transducer (4), whereby an incremental detector serves as a detector (9, 23) for progressively detecting the movement (S). The distances (&dgr;, &dgr;&agr;) between individual image partial areas (6) can be then be determined by evaluating the progressively detected positions of the ultrasound transducer (4) which are then assigned to the individual image partial areas (6).
