Intelect® Mobile Ultrasound
Common Terms
Applicator - The hand held assembly used to deliver ultrasonic energy. The applicator includes the sound head, transducer, and
related electronics.
Beam Non-Uniformity Ratio (BNR) – By nature, an ultrasound beam is not homogeneous. The BNR is a ratio of the highest intensity
found in the beam field to the average intensity as indicated on the output display of the unit. This measure may not exceed 5.0:1.
Because of the areas of increased intensity, the sound head is moved continuously during the treatment.
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.
Utilizing ultrasound waves through muscle, nerve, and connective tissue has been well documented as effective in reducing pain,
muscle spasms, and joint contractures.
There are several items that affect the penetration of ultrasound on the target tissues. Please refer to the documentation as a
reference on the appropriate frequency for your clinical needs.
There are four sound heads available with the Intelect Mobile Ultrasound System: 1 cm2, 2 cm2, 5 cm2, and 10 cm2.
Select either 1 or 3 MHz frequencies for each applicator (only 3.3 MHz is available with the 1 cm
2
sound head). Frequency may be
selected either before or during therapy.
OVERVIEW OF ULTRASOUND THERAPY
ABOUT ULTRASOUND THERAPY
8
Intelect® Mobile Ultrasound
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 ultrasound. The lower the percentage, the lower temporal average intensity. 100% is continuous ultrasound.
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/cm2.
Frequency (Freq) – Selectable to 1 or 3 MHz with the 1 cm2, 2 cm2, 5 cm2, or 10 cm2 sound head (only 3.3 MHz is available with the
1 cm
2
sound head). The lower the frequency, the longer the wavelength, the deeper the penetration of ultrasound.
Lead Zirconate Titanate – A synthetic crystal used to create the ultrasound beam by vibrating 1,000,000 (1 MHz) or 3,000,000
(3 MHz) times per second. This type of crystal is both durable and efficient in its functions.
Power – A measure of the intensity of the ultrasound delivered to the patient. Unit of measure is watts (W).
Pulse Duration – Refers to the amount of time the ultrasound is being delivered in the pulsed mode. For example, in the 20% duty
cycle mode, the ultrasound is delivered for 2 msec and off for 8 msec (at 100 Hz) throughout the treatment period.
Pulse Frequency – The pulse frequency is the number of pulses per second and is expressed in hertz. The available pulse
frequencies on the Intelect Mobile Ultrasound are 16, 48, and 100 Hz.
Pulsed Mode – The output of the ultrasound is automatically interrupted during the treatment time. This limits the amount of
energy delivered to the tissues.
Sound Head – The aluminum face of the applicator that contacts the patient’s skin. It covers a transducer mechanism that converts
electrical energy to mechanical energy in the form of a vibrating crystal.

Intelect® Mobile Ultrasound
OVERVIEW OF ULTRASOUND THERAPY - COMMON TERMS (CONTINUED)
Ultrasound Intensity – Ultrasound power delivered to the patient expressed in total power as watts (W) or in terms of the sound
head’s effective radiating area, watts per centimeter squared (W/cm2).
Description of Ultrasonic Field
The spatial distribution of the radiated field is essentially a collimated beam of the ultrasonic energy having a cross-sectional area of
8.5 cm2 for the 10 cm2 sound head when measured at a point 5 mm from the transducer face.
The energy distribution within the radiated field is 3.0 W/cm2 maximum and it takes a generally conic shape, having decreasing
intensity at progressively increasing distance from the face of the transducer. This field distribution applies for the radiation emitted
into the equivalent of an infinite medium of distilled, degassed water at 30 °C and with the line voltage variations in the range of 10%
of the rated line voltage.

been diagnosed.
•This device should not be used when cancerous lesions are
present in the treatment area.
•This device should not be used when open wounds are present
in the treatment area.
•This device should not be used on patients suspected of
carrying serious infectious disease and or disease where it is
advisable, for general medical purposes, to suppress heat or
fevers.
•This device should not be used over or near bone growth
centers until bone growth is complete.
•This device should not be used over the thoracic area if the
patient is using a cardiac pacemaker.
•This device should not be used over a healing fracture.
•This device should not be used over or applied to the eye.
•This device should not be used over a pregnant uterus.
•This device should not be used on ischemic tissues in individuals

to follow the increase in metabolic demand and tissue necrosis
might result.
ADDITIONAL PRECAUTIONS
Additional precaution should be used when the ultrasound is used
on patients with the following conditions:
•Over an area of the spinal cord following a laminectomy,
i.e., when major covering tissues have been removed.
•Over anesthetic areas.
•On patients with hemorrhagic diatheses.
ABOUT ULTRASOUND THERAPY
11
Intelect® Mobile Ultrasound
Potential for Burns
It is possible for ultrasound therapy to cause burns if the therapy is
not performed properly. Skin burns can result from one or more of
the following:
•If the intensity (power) is too high.
•If you are using too low a frequency.
•Using a stationary technique (holding the sound head in one
place).
•Moving the sound head too slowly.
•Treating an area with sensory nerve damage (or the loss of
normal skin sensations).
•Desensitized areas can be overheated or burned without the
patient’s knowledge. Use extreme caution with these patients
(e.g., diabetes, neural damage, etc.).
•Bony prominences are especially vulnerable: they reflect sound
waves and increase intensity to the periosteum.
ABOUT ULTRASOUND THERAPY
DANGER
Patients with an implanted neurostimulation device must not be
treated with or be in close proximity to any shortwave diathermy,
microwave diathermy, therapeutic ultrasound diathermy or
laser diathermy anywhere on their body. Energy from diathermy
(shortwave, microwave, ultrasound and laser) can be transferred
through the implanted neurostimulation system, can cause tissue
damage and can result in severe injury or death. Injury, damage or
death can occur during diathermy therapy even if the implanted
neurostimulation system is turned "off."
12
Intelect® Mobile Ultrasound
Preventing Overheating of the Sound Heads
To prevent the sound head from becoming overheated, do the
following:
•Check to be sure proper contact is being made throughout the
treatment.
•When treating in water, make sure that the sound head is
completely under water.
•For direct coupling, you may need to apply more conductive gel
or lotion during the treatment to achieve better coupling.
•You can also reduce the power or duty cycle during the
treatment if you are treating an area where it is difficult to obtain
good coupling.
Preventing Adverse Effects
Perform the following procedures to avoid the negative effects of
ultrasound therapy.
Sound Head Movement
If movement of the sound head is too slow, the patient may feel
periosteal pain characterized by a deep ache or pain. If motion is
too fast, or if the sound head does not maintain good contact with
the skin, the therapeutic effect of the sound waves will be reduced
and the sound head may overheat.
Patient Susceptibility
Some patients are more sensitive to ultrasound output and may
experience a reaction similar to a heat rash. Be sure to inspect the
treatment area during and following treatment, and discontinue if
an adverse reaction does occur.
Output Power
Choose a lower watt setting to reduce output or select a pulsed
duty cycle. Higher output levels have a greater potential for patient
discomfort.
Coupling
Coupling is described as contact between the sound head and
the treatment site and may be accomplished through the use of a
coupling agent, such as gel, lotion or water (underwater treatments
only). Anything used as a coupling agent must be highly
conductive. Air is a very poor conductor of ultrasonic waves.
Head Max. Temp. Disclaimer
