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 ...
Caracterização morfológica da corrosão por pite da liga AL2024 em soluções contendo cloretos e molibdatos
(2003-12-01)
A very new method application for digital image processing and analysis to classify shape and evaluate size and morphology parameters of pit corrosion is used in this paper. This method seems to be very effective to analysis ...
