Our experience is: phased array is much better than RT. RT could not clearly reveal the mico crack in the fir-tree design of turbine blades. But with phased array, we could get all the quantitative details (length, breadth, depth) accurately and could image the micro-crack also clearly.
All the best,
best regards,

Does standard allow us to do so?
what is its advantages?
thank you in advance
