Method and system for inspecting objects using ultrasound scan data

A method and apparatus for estimating a depth of a crack (40) from ultrasound scan data are provided. The method includes mapping multiple amplitude responses from the ultrasound scan data, each mapped amplitude response being representative of a signal from one of the sensors (34, 36, 38). The meth...

More Information
Summary:A method and apparatus for estimating a depth of a crack (40) from ultrasound scan data are provided. The method includes mapping multiple amplitude responses from the ultrasound scan data, each mapped amplitude response being representative of a signal from one of the sensors (34, 36, 38). The method further includes locating multiple linear responses among the mapped amplitude responses, each linear response being an indicator of a reflected signal from the crack. One or more sensor (34, 36, 38) that corresponds to the linear responses from a given crack (40) is identified. The depth of the crack (40) is estimated using data from the identified sensors.
