Improving synthetic aperture image by image compounding in beamforming process
(2011-11-10)
In this work, signal processing techniques are used to improve the quality of image based on multi-element synthetic aperture techniques. Using several apodization functions to obtain different side lobes distribution, a ...
Ultrasonic Image Compounding Method Based on the Instantaneous Phase Image
(Ieee, 2016-01-01)
The quality of ultrasonic images depends on array configuration, image beamforming algorithm, propagation modes and signal-to-noise ratio. Some alternatives to improve image quality are related to the use of coherence ...

Lamb mode diversity imaging fornon-destructivetesting of plate-likestructures
(London, 2014-02-24)
Several Lamb wave modes can be coupled to a particular structure, depending on its geometry and transducer used to generate the guided waves. Each Lamb mode interacts in a particular form with different types of defects, ...

Spatial image compounding applied to a phase coherence corrected UT-PA technique for inspecting nuclear components of coarse-grained structure
(The American Institute of Physics, 2016-02)
The aim of this work is to obtain a C-Scan view of an austenitic stainless steel weld from a nuclear use pipe. In order to obtain this result Sectorial Scans (S-Scan) from both sides of the weld are obtained by Ultrasonic ...
