Visibilty of IQI

Is there any possibility of seeing more IQI wire than recommended as per code in X ray radiography, If yes, what are the possibilities?

Yes, use as low a kV as possible, smallest focal spot size available, maximum source-film distance and slowest film speed available and you will have an excellent but highly uncommercial radiographic image with more wires visible than any Code committee ever dare stipulate.

To continue with Nigels thread....

....and place the IQI on the film side of the object, taped in close contact with the film cassette. You could also use an IQI made of denser material than the material being examined but don't forget to take out the IQI identification tag and replace it with....

You understand that I am NOT being serious. I do wonder though why you would want to produce radiographs of a better than required sensitivity.

oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field

...
nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
