title: Repetitive echoes in ultrasonography of the diaphragm demonstrated by cadaver studies.
abstract: For some years past, strange and seemingly inexplicable images frequently appear during sonographic examination of the area below the diaphragm. In order to explain these mysterious phenomena we carried out anatomical experiments. We observed the appearance of such enigmatic images no matter what the kind of probe was used and found that in every case the appearance of a phantom image over the diaphragm signifies the existence of a true image situated elsewhere. It is always possible with necessary adjustments to locate the formation responsible for the phantom images, which are no longer mysterious.
