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.

Method for dynamic testing using ultrasonic imaging

An automated device for non-destructive testing for the detection of defects of a complex tubular product includes at least one ultrasound transducer arranged to emit an ultrasound beam having an emission orientation. The automated device further includes control and processing electronics configured to define at least one ultrasound burst parameter as a function of the longitudinal and/or circumferential position of the ultrasound emission means, so as to detect defects in the tube wall. The at least one parameter being chosen from the burst emission orientation, the gain or the position of the temporal filter.
