WebIn magnetic resonance, a spin echo or Hahn echo is the refocusing of spin magnetisation by a pulse of resonant electromagnetic radiation. Modern nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) make use of this effect.. The NMR signal observed following an initial excitation pulse decays with time due to both spin relaxation … WebNDT Testing Our Services Ultrasonic Testing – Pulse-Echo Method. The method is based on mechanical waves (ultrasound) generated by a piezo-magnetically excited element at a frequency typically in the range between 2 and 5 MHz. Control involves the transmission, reflection, absorption of ultrasonic propagated wave in the controlled part.
