* SATP
= Spatial Average Temporal Peak (average pulsed power)
* ERA
= Effective Radiating Area, this is the effective radiating area of the treatment head.
* BNR
= Beam Nonuniformity Ratio, indicates the ratio between the peaks and the average value of the
intensity in the sound beam. A low BNR excludes high, unwanted energy concentrations.
ERA and BNR are measured confirm the FDA- method. All treatment heads have a visual contact control.
