(3) Default setting for acoustic power
24.1.5 Output display
This system displays thermal and mechanical indices in real-time. The display
conforms to IEC 60601-2-37, "Particular requirements for the safety of ultrasonic
medical diagnostic and monitoring equipment."
The display is intended to give the user information related to the likelihood of bioeffects
from tissue/bone heating (TI) and cavitation (MI). The user should practice ALARA (As
Low As Reasonably Achievable) with respect to these indices.
The maximum acoustic intensity with any transducer/system combination will remain
below the FDA (Federal Food and Drug Administration) limit of 720 mW/cm
either 1.9 MI or 190 W/cm
For additional information on bioeffects beyond that contained in this labeling, contact
your TOSHIBA service representative. As further information becomes available on the
potential for bioeffects, these displays may change.
24.1.6 Reminder
As a reminder, Always Practice ALARA. The display gives information in real time
and therefore shows the current acoustic exposure rates to the tissue or structure being
insonated.
For inquiries and information, contact your TOSHIBA service representative.
Additionally, as further information becomes available, we will do our utmost to keep
you informed.
