Tissue Characterization

  • Eugenio Picano

Abstract

Echocardiography shares the same principles present in nature in the sonar of bats and dolphins. These animals send out an ultrasonic signal and — based on the arrival time of the reflected ultrasound wave — can detect reflecting structures, locate them in space, and perceive their form and motion. However, animal sonar has a greater potential than is dreamt of in commercially available instruments, since bats and dolphins can differentiate edible from inedible reflecting structures [1]. From the captured echo, they extract information on the internal composition of the target. In the same way, the underlying hypothesis in tissue characterization studies is that a different biochemical structure or internal architectural arrangement of normal versus diseased tissue can affect the physical properties of the tissue and can therefore be detected by ultrasound [2].
