endoscopic ultrasonography meaning

  "endoscopic ultrasonography" in a sentence
Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals,which pass through the electronics of the instrument,into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The endo- of endosonography refers to the examination of tissue within hollow organs,with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.
