SAFT Processing for Manually Acquired Ultrasonic Measurement Data with 3D Smartinspect

We describe the implementation and architecture of a system for Synthetic Aperture Focusing Technique reconstruction on ultrasonic data acquired by a handheld device. The reconstruction is performed simultaneous to the measurement process and instantaneous highly focused visual feedback is provided to the engineer. The implementation is based on the 3D smartInspect system that is currently being developed at Fraunhofer IZFP. This system assists engineers by recording, displaying and protocolling manually acquired data. We show that it is possible to enhance this system by adding simultaneous Synthetic Aperture Focusing Technique processing on top of the existing functionality. This leads to an improved imaging quality of the system, increasing its feasibility for difficult measurement tasks and lowering the demands on the measuring engineer even further.
