Measurement of shadow zone

Hi !
Do anybody know a method to measure the lateral shadow zone in immersion testing technique ?
In fact, we inspect premachined forgings part in titatnium or Ni-base alloys and sometimes I'm thinking that the premachined shape is not optimized for immersion UT inspection.
I think that is very important to know the dimension of shadow zones, induced by geometry (like thickness change...) to permit the good inspection of the finish part, included in premachined shape.

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?
