Digital Image Correlation of 2D X-ray Powder Diffraction Data for Lattice Strain Evaluation
High energy 2D X-ray powder diffraction experiments are widely used for lattice strain measurement. The 2D to 1D conversion of diffraction patterns is a necessary step used to prepare the data for full pattern refinement, but is inefficient when only peak centre position information is required for lattice strain evaluation. The multi-step conversion process is likely to lead to increased error...
متن کاملUncalibrated X-Ray Stereo Reconstruction
We describe a novel application of uncalibrated stereo reconstruction to Roentgen Stereophotogrammetry Analysis (RSA). In RSA, stereo X-ray images are taken of a bone containing a prosthesis (e.g. a replacement knee) and a number of metal markers. The aim is to recover the relative position of the prosthesis and markers in 3D. Accuracy in previous RSA methods has been limited by two factors: ma...
متن کاملfuzzy-based medical x-ray image classification
in this paper a novel fuzzy scheme for medical x-ray image classification is presented. in this method, any image is partitioned in to 25 overlapping subimages and then shape-texture features are extracted from shape and directional information extracted from any subimage. in the classification stage, we apply a fuzzy membership to any subimage with respect to euclidean distance between feature...
متن کاملDigital image acquisition and processing in medical x-ray imaging
This contribution discusses a selection of today's techniques and futurc concepts for digital x-ray imaging in medicine. Advantages of digital imaging over conventional analog methods include the possibility to archive and transmit images in digital intormation systems as well as to digitally process pictures before display, for example, to enhance low contrast details. After reviewing two digi...
متن کاملDigital Image Processing: Automated X-Ray Inspection in Electronics Manufacturing
In this paper, we examine two dimensional transmission and three dimensional laminography, as implemented in two Automated X-Ray Inspection (AXI) industrial machines used for inspection of Surface Mount Technology (SMT) solder joint connections in electronics manufacturing: the Teradyne XStation and Agilent 5DX. Factors affecting xray image quality, such as the size of the focal spot, the x-ray...
