<p>The system (10) has an ultrasonic head (1) attached to a surface of an object that is sonographed and changed into a specific position. A projector (2) i.e. laser, is utilized for projection (5) of a marking i.e. cross unit, on the object. A coupling device (3) couples the projection at the position of the ultrasonic head. The marking is formed at a predetermined position on the object if the ultrasonic head lies at the object in a correct position. A projection direction is varied and coupled to the position of the ultrasonic head.</p> |
