Embodiment Construction

[0024] Phased array is an ultrasound technique used for non-destructive evaluation applications. Since data captured from one location only characterizes the flaw at a particular angle of incidence, and non-diffused flaws may not be captured from this angle, the flaw information needs to be captured from a different location.

[0025] According to an embodiment of the present disclosure, a 3D reconstruction for phased array based non-destructive evaluation application enables data analysis using fused information from multiple capture locations and provides for crack detection and shape estimation Foundation.

[0026] Embodiments of the present disclosure include a more accurate reconstruction method using splatting, a faster reconstruction method for data browsing, and a parallel reconstruction method. Embodiments of the present disclosure further include methods for handling volumes that exceed memory and volume renderer limitations.

[0027] In this specification, the pre...

Abstract

The invention discloses an image reconstruction method, comprising: receiving volume data (410) containing multiple sampling points; determining a first adjustment (411) to suppress low amplitude and preserve the sampling point with the largest amplitude; determining a second adjustment to the sampling point Conditioning, wherein the influence of a sampling point depends on its distance from a grid point in the sampling grid (412); determining a kernel comprising a plurality of weighting functions for the first conditioning and the second conditioning, in order to determine the energy spread of each without determining the shape or size of the core (413); and outputting a reconstructed volume based on the energy spread of each of the plurality of sampling points (414).

Description

[0001] Cross References to Related Applications [0002] This application is a non-provisional application claiming priority to US Provisional Application Serial No. 61 / 387,155 filed September 28, 2010, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to image reconstruction, and more particularly to methods for reconstructing phased array data. Background technique [0004] In a phased array, multiple ultrasound transducers are arranged in an array. Each transducer in the array can be driven individually. By using delay and amplitude patterns, an array of transducers can be used to form specific beams. The retardation patterns and amplitude patterns (also known as laws) used are often grouped under the term focal law. Different focal length rules can be used to form beams that not only focus on points at different distances, but also form beams at different angles. Phased array devices capture reflected si...
