Clinical Safety
There are no confirmed biological effects on patients or equipment operators caused by
exposure from existing ultrasound equipment in the market.
Ultrasound Safety
Biological interaction and Ultrasound Bio-effects
As ultrasound energy is propagating into the body, the soft tissue absorbs or scatters some of
the energy. The scattering of ultrasound energy may cause reflections or echoes on the
spectrogram. Absorption of ultrasound energy may cause tissue damage by one or a
combination of two methods: a mechanical mechanism which may include cavitation and a
thermal mechanism that causes heating. Following As Low as Reasonably Achievable (ALARA)
mitigates the possibility of any of these mechanisms occurring.
ALARA
When using the NovaGuide™, the principles of ALARA should always be followed. ALARA is the
acronym for As Low As Reasonably Achievable. This principle simply states that the operator
should keep the ultrasound output levels and exposure times as low as possible while still
obtaining the desired cerebral blood flow velocity information.
Power Controls for Acoustic Output
The Power setting on the NovaGuide™ is the only user control that directly affects the transmit
power level for the selected channel. The adjustments are made in steps from 0 to 100%. Power
can be increased when Doppler signals are considered to be too weak and decreased when the
signals are satisfactory.
Adjustments to the sample volume size or depth settings affect the pulse repetition frequency
(PRF) of the Doppler transmit signal. The system automatically adjusts the acoustic output pulse
amplitude in order to maintain the set power level.
The acoustic output should be adjusted in accordance with the ALARA principle by starting the
exam at a low power setting and then increasing the power level as necessary until the desired
diagnostic information is obtained.
For the eye, foramen magnum, burr holes and fontanelles, a precaution is displayed to the user
during entry into any exam screen which states to use 10% or lower power levels.
When selecting any of the ophthalmic vessels, including siphons (ROPTH, LOPTH, LSIPHN,
RSIPHN) the NovaGuide™ will automatically set the power setting to 10%.
Managing Ultrasound Exposure
As previously stated, ultrasound energy may cause tissue damage due to mechanical or thermal
mechanisms. To assist users, thermal and mechanical indexes are modeled to represent relative
