*SATP = Spatial Average Temporal Peak (average pulse 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 have been measured according the FDA-method. All treatments heads have been provided
with contact control.
