High mechanical index
Webusing low–mechanical index (MI) harmonic imaging has been available on all ultrasound systems marketed within the past decade, and real-time very low MI techniques are available on nearly all commercially avail-able systems. By definition, very low MI represents values < 0.2, low MI represents values < 0.3, intermediate MI represents values
