Abstract:
1. An ultrasound probing device, comprising: a box; locating means to provide a position of the box in relation to a reference frame associated with an object to be examined; means for determining a delay law on the basis of focusing parameters representing a desired position of a focal point in relation to a reference frame associated with the box; control means to provide control signals on the basis of the delay law; transducers attached to the box, to receive control signals and, in response, to transmit ultrasonic waves in the object which are delayed with respect to each other according to the delay law such that the ultrasonic waves focus at the focal point defined by the focusing parameters; and means for updating the focusing parameters based on predefined associations between positions on a desired path of the box in relation to the reference frame associated with the object and the corresponding focusing parameter values and the position of the box.
