About Diagnostic Techniques
It is the procedure or method used for recognize the disease or disorder function or disability. The procedure or method used includes the laboratory tests and the imaging techniques like the Radiology, Ultra sound etc. The laboratory tests include the test relating to diagnosis of infectious agents. In the diagnostic techniques that we use, two different classes can be distinguished: passive techniques (spectroscopy) and active ones. In the former case, the radiation from the plasma is studied. This is a very old technique, and technically relatively simple. Interpretation of the results, however, can be complicated. In the latter case, some interaction with the plasma takes place, for example, a laser beam is pointed at the plasma. This can offer much more direct information about the plasma, but is more demanding on the experimental setup
