4.2.6 Parameters ultrasound therapy
Ultrasound Frequency
, expressed in MHz, is the frequency of the ultrasound waves. The ultrasound
frequency determines the penetration depth, which has the largest value at 1 MHz. The ultrasound
frequency can be set at 1 MHz or 3 MHz.
Duty Cycle
, expressed in %, defines the ratio of the pulse duration to the pulse repetition time.
Ultrasound can be applied in pulsed or in continuous mode. When the Duty Cycle is set to 100%, the
apparatus operates in continuous mode.
Effective Radiation Area
(ERA) expressed in cm², defines the cross-sectional area of the ultrasound
beam (See technical specifications for details). The Effective Radiation Area is fixed and defined by the
size of the ultrasound applicator.
Ultrasound Power
is the ultrasound output expressed in W. The ultrasound output display can be
toggled between W and W/cm². In pulsed mode the power during the pulse is displayed. The time
averaged power can be obtained by multiplying this value with the Duty Cycle.
Ultrasound Amplitude
, expressed in W/cm², is the quotient of Ultrasound Power and Effective Radiation
Area. The ultrasound output display can be toggled between W and W/cm². In pulsed mode the
Amplitude during the pulse is displayed. The time-averaged Amplitude can be obtained by multiplying this
value by the Duty Cycle.
4.3 Combination Therapy
Combination therapy is the combined application of ultrasound and electrical stimulation. With
combination therapy the metal surface of the ultrasound applicator becomes the negative electrical
stimulation electrode, while the lead wire with the red connector remains the positive electrical stimulation
electrode. Combination therapy is available with all current waveforms, but limited to channel 2.
Combination therapy is typically used for the reduction of muscle spasm.
The combined Contra-indications and Adverse Effects of paragraph 4.1 and 4.2 apply.
