3D image

To prepare simulated free-of-noise 3D images of a complex body For this target the image of an internal pore in the real welding joint with extracted noise was used. The ray tracer model was applied for the simulation of five projections of the selected image. 

A software has been elaborated allowing the automation of this control and the reconstitution of 2D and 3D images of the controlled samples.

New Eddy Current Probe and Associated Preprocessing for 3D Image Reconstruction in Non Ferromagnetic Tube Testing. 

Progress in mean of modelisation and inverse problem solving [1] let us hope to dispose soon of these tools for flaws 3D imaging in Non Destructive Control with eddy current sensors. This will achieve a real improvement of the actual methods, mainly based upon signature analysis. But the actual eddy current probes used for steam generators tubes inspection in nuclear industry do not produce the adequate measurements and/or are not modelisable.

D-TEM gave 3D images of nano-filler dispersion in NR, which clearly indicated aggregates and agglomerates of carbon black leading to a kind of network structure in NR vulcanizates. That is, filled rubbers may have double networks, one of rubber by covalent bonding and the other of nanofiller by physical interaction. The revealed 3D network structure was in conformity with many physical properties, e.g., percolation behavior of electron conductivity.

At this point it is essential to compare the calculated structure with both the experimental data and the results of the rMD run (6). On the one hand, the interatomic distances of the final model must match the NMR restraints additionally, the fMD-averaged structure should correspond with the refined conformation obtained by the rMD. Only if the rMD and the fMD simulations result in the same conformational model and no experimental restraints are severely violated the calculated structure can be presented as a 3D image (7).

The bottom image in Figure 2.2.15 is a maximum intensity projection of a 100 xm cubic-resolution 3D-image dataset of a blue berry acquired with this system. The network structure of the fruit is clearly visualized. If the MRI console and permanent magnet can be made smaller, a true desktop or handy M R microscope will then be constructed. 

Cano Barrita [27] cast concrete specimens with w/c of 0.6, dried the specimens at 38 °C and 20% relative humidity, then measured the penetration of water in a capillary uptake type of experiment. A 3D centric scan SPRITE measurement was selected, as an image could be acquired in 150 s and the image would therefore be weighted only by the T2 decay. 3D images were acquired at various exposure times and the central 2D image slice was extracted from the data to measure the penetration depth with time.
