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.
