Abstract
Configuration of an ultrasonic inspection system is facilitated using an ultrasound response predicted by a simulation tool. In one embodiment, estimated material properties of an object to be inspected are input to the simulation tool. Also input to the simulation tool is at least one estimated property of an ultrasonic transducer of the ultrasonic inspection. The simulation tool predicts the response of the object to ultrasound from the ultrasonic transducer. This response is dependent upon the estimated material properties of the object to be inspected and the at least one estimated property of the ultrasonic transducer. The ultrasonic inspection system is then configured dependent upon a feature of the predicted response. The system may be configured, for example, by setting the position of a time gate, selecting an appropriate ultrasonic transducer, selecting the position of the transducer to achieve good focus, or selecting parameters for signal processing.
