8.. When using ultrasound, a moving head technique is recommended to avoid the buildup of “Hot Spots" or standing
waves which might lead to tissue damage.
9.. To start the treatment, supply adequate coupling, apply the transducer to the patient and increase the power. Adjust
the output intensity - typically to a range of 0.5W/cm
2
to 1.5W/cm
2
based on patient comfort. The treatment time
will automatically adjust based on the power setting chosen to provide the correct dosage. As the power is
increased, the time decreases and vice versa. If the patient experiences any discomfort, decrease the power by a
small amount (0.1 - .2W/cm
2
) and note if the pain is reduced. If so, continue the treatment.
Note:
The Delta T mode of operation is calibrated for muscle not in proximity of bone. If the ultrasound application at
3MHz is within 1 cm of bone the 2-Delta T mode will heat at a rate of 4 °C, or the 1-Delta T mode will heat at 2
°C. Within .5cm proximal to bone, the 1-Delta T mode will heat at 4 °C due to the reflection of the ultrasound
field from the bone back into the overlying tissue.
10. Reduce the output power if the patient complains of pricking sensations, “pins and needles” or painful temperature
changes. Induced pain is also a good indication that the dosage level is too high. This sensation may indicate
periosteal heating and should be avoided as significant tissue damage may occur under prolonged treatment
application.
11. Proper personnel training on use of ultrasound and the equipment is essential in order to ensure high standards of
therapy.
12. Avoid operator exposure to the ultrasonic field.
