Abstract: This implementation method is used for an ultrasound scanner including an ultrasound scanner probe used to explore an area of interest on the human body, in which a drive system including a stepper motor and a carrier supporting a transducer element is controlled in order to pick up echo lines via the transducer element. An imaging algorithm is applied and image points are analyzed along an arc at a given depth for two series of successive emission and return echo lines, in order to determine the angular offset of the image points in the two successive arcs and calculate the angular offset of the emission echo lines and return lines induced by the operation of the drive system, and then offset is corrected.
