Fig. 1.11 Microwell array ECL images showing detection of PSA and IL-6 in mixtures in calf serum, obtained at 0.95 V vs Ag/AgCl using 0.05% Tween 20 + 0.05% Triton-X 100 + 100 mM TprA, pH 7.5. RuBPY-silica nanoparticles were used with antibodies attached for both proteins a (1) 5 ng mL-1 PSA, (2) 1 ng mL-1 IL-6 , b (1) 0.4 ng mL-1 PSA, (2) 0.2 ng mL-1 IL-6, (c) (1) 40 pg mL-1 PSA, (2) 20 pg mL-1 IL-6, and (d) (1) 1 pg mL-1 PSA, 2) 0.25 pg mL-1 IL-6. In all images, controls are indicated by duplicate spots (3) 0 pg mL-1 IL-6, and (4) 0 pg mL-1 PSA. E and F are comparison of ECL array determinations of PSA and IL-6 in patient serum with individual ELISAs e IL-6 f PSA. Samples 1 to 4 from prostate cancer patients samples 5 and 6 were from cancer-free patients. Reproduced with permission from ref. [101] copyright American Chemical Society 2011...

Image-control functions are intended to read and write settings, such as parameters for gain and exposure time. 

Homogeneity of data. Homogeneous data will be uniform in structure and composition, usually possible to describe with a fixed number of parameters. Homogeneous data is encountered in simple NDT inspection, e.g. quality control in production. Inhomogeneous data will contain various combinations of indications from construction elements, defects and noise sources. An example of inhomogenous data are ultrasonic B-scan images as described in [Hopgood, 1993] or as encountered in the ultrasonic rail-inspection system described later in this paper.

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

Un logiciel a etd elabore, permettant d automatiser ce controle et de reconstituer des images a deux et trois dimensions des echantillons controles. 

Coating control and evaluation by the restitution of the coated structure image. 

The sweeping test, following X, Y and Z axes, on the aluminum plate containing four standard defects and the processing software comparing between the impedance variation of the sane reference and the sample to be controlled allow the reconstitution of an image of the piece. 

II serait done ainsi facile d obtenir en temps reel sur ordinateur, I image d un defaut standard long qui est a meme de produire la variation d impedanee observee. II serait ainsi possible de realiser le controle par des mesures absolues et d eviter le recours a des defauts etalons. 

It would be tlierefore thus easy to obtain in real time, on computer, tlie image of a long standard defect that is to even to produce the impedance variation observed. It would be thus possible to realize the control by absolute measures and to avoid the recourse to standard defects. 

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.

In general, the performance of a radioscopic system should always be checked via test pieces with natural flaws. To ensure an additional comparability, standardized image quality indicators have to be used to control the essential image quality parameters such as spatial resolution (unsharpness) and contrast sensitivity. 

Of all NTD methods for quality control of materials, products, welded and soldered joints the most informative and perspective are radioscopic ones that enable to obtain a visual image of an inner structure of a tested objects in real time under any projection.
