      Tissue harmonic ultrasonic imaging 

      Averkiou, Michalakis A. (2001)
      Harmonic imaging was originally developed for microbubble contrast agents in the early 90s under the assumption that tissue is linear and all harmonic echoes are generated by the bubbles. In fact, tissue, like bubbles, is ...
