Reconstruction section images

In this paper, discontinuities in cylindrical specimens were studied by ultrasonic reflection tomography. The aim was threefold. First, to localize discontinuities from circular C-scan images. Second, to reconstruct quantitative cross-sectional images from circular B-scan profiles (i.e., reflection tomograms). Finally, to obtain three-dimensional information (i.e., discontinuity location, dimension and type) by stacking these reflection tomograms in multiple planes, in the third dimension. 

The analyze mode display is similar to the scan mode display used online. Analyze mode includes functions for evaluation of data, e. g. markers, measure functions, zoom function and selection of cross-section views. In addition, A-scan data can be reconstructed into images and displayed.

Mass spectrometry imaging (MSI) circumvents these issues by combining MS with microscopy (5). Spatially resolved mass spectrometric experiments directly on the surface of tissue sections enable the reconstruction of images and therefore the localization of hundreds of molecules within their histological context without any labeling. MSI has therefore received considerable interest as an imaging technique for the ex vivo molecular interrogation of animal, human, or plant tissue sections (6).

Because a cell is a three-dimensional entity that changes shape in the X, y, and z axes as it crawls, it is necessary to perform 3D reconstructions in order to get accurate information on the behavior of particles attached to the cell surface. To measure the trajectories and compute 3D parameters of microspheres attached to the surface of Dictyostelium amoebae, optical sectioning, image acquisition, and outlining using trace slots are performed as described... 

In order to reconstruct the image information, an adequate spectral width is needed for the probe beam to satisfy the Bragg condition at every grating component. In this section, we will theoretically estimate such a spectral width. When we rewrite Eq. (9) using the deviation vectors Sea, the difference between jUi and jUo is given by...

All CT or MRI techniques that provide high-resolution, cross-sectional images, or volumetric data acquisition, can be post-processed to obtain 3D reconstructions and VL.
