About this document

Near and Far Field in Ultrasound by Momo Itachi is a document available to read on EtoBox.

Round transducers emit sound from most of their surface like a piston, creating a cylindrical sound field with constructive and destructive interference near the source (near field). Beyond the near field distance (N) is the far field where the beam is more uniform. For optimal flaw detection, flaws should occur just beyond the near field where the sound wave is at its maximum strength. The near/far field transition point (N) can be calculated using the transducer
