The table gives some indication of typical (or average) half value depths for therapeutic ultrasound [18] . As it is difficult, if not impossible to know the thickness of each of these layers in an individual patient, average half value depths are employed for each frequency: 3MHz - 2.0cm; 1MHz - 4.0cm. 1MHz.
