Nonetheless, ultrasound is a form of energy and, as such, demonstrates effects in biological tissues it traverses (bioeffects). The physical mechanisms responsible for these effects are thermal or non-thermal (mechanical). Webbiologic effects can occur, but studies have failed to pro-vide conclusive evidence that sonographic exposure causes damage to human tissue. The assumption that sonograms are safe to perform on humans is based not on safety data but predominantly on a lack of evidence of harm.
