Collimating (Coll)
- The shape of the ultrasound beam. While neither focused nor dispersed, this ultrasound beam resembles a column
when applied from the unit through the sound head.
Continuous Mode
– The output of the ultrasound is not interrupted during the treatment time. This mode imparts the most energy to
the tissues and is used when a maximal effect is desired. (
See Duty Cycle
).
Coupling Media
– An agent used to insure that the ultrasound is transmitted from the sound head to the tissue to be treated. Gels or
lotions labeled for therapeutic ultrasound use are recommended.
Cycle Time
- Cycle Time is the alternating time which the current is "on" and "off." Using the 10/30 setting as an example, the current is on
for 10 seconds and off for 30. The available cycle times are Continuous, 5/5, 4/12, 10/10, 10/20, 10/30, and 10/50.
Display
- Available only on the High Voltage Pulsed Current (HVPC) waveform, the Display feature allows you to change the displayed
Intensity parameter from Volts to Peak Current (Amps).
Duty Cycle
- This is the ratio of the “On” time to “Total” time of the cycle, expressed as a percentage. The duty cycle describes the pulsed
modes of electric stimulation and ultrasound. The lower the percentage, the lower temporal average intensity. 100% is continuous
electrotherapy. The available Duty Cycles are 10, 20, 30, 40, 50%.
Effective Radiating Area (ERA) –
A measure of the ultrasound beam made underwater, 5 mm from the radiating surface of the sound
head. The ERA is always smaller than the geometric area of the sound head, but should be as close as possible. This measurement is used
to calculate the ultrasound intensity in W/cm
2
.
Frequency (Electrotherapy)
- Frequency is the number of times per second a pulse, cycle, burst, or beat will repeat itself. The unit is
selectable from 1-200 Hz (beat), 20-100 Hz (burst), and 2000-5000 Hz (carrier).
Frequency (Ultrasound)
– Selectable to 1 or 3.3 MHz with the 2 cm
2
, 5 cm
2
, or 10 cm
2
sound head (excluding the 1 cm
2
sound head).
The lower the frequency, the longer the wavelength, the deeper the penetration of ultrasound.
Frequency Modulation (Freq. Mod.)
- This is the rhythm at which a frequency changes. The available frequency modulations are 0 to
250 Hz in increments of 5 Hz.
