Abstract: A method for dynamically acquiring data representing a part to be tested, the method includes a multi-element sensor acquiring data concerning the part to be tested, transmitting an ultrasonic shot, receiving a returned wave returned by the part resulting from the ultrasonic shot, generating data representing the part to be tested, and during the data acquisition step, a relative movement between the sensor and the part to be tested, the method further includes generating corrected data representing the part to be tested by simulating a relative movement between the sensor and the part to be tested up to a reference position.
