Safety statement
GE Vingmed Ultrasound safety statement
Although no harmful biological effects have been demonstrated
for ultrasound frequencies, intensities and exposure times used
in examination with the GE Vingmed Vivid i system, GE
Vingmed Ultrasound recommends using the lowest acoustic
output settings which will produce diagnostically acceptable
information.
System controls affecting acoustic
output
The operator controls that directly affect the acoustic output are
discussed in the Acoustic Output Data Tables in the Reference
Manual. These tables show the highest possible acoustic
intensity for a given mode, obtainable only when the maximum
combination of control settings is selected. Most settings result
in a much lower output. It is important to note the following:
•

Probe selection
As long as the appropriate application is available, any probe
can be used with the knowledge that the intensities fall at, or
below, those stated in the Acoustic Output Data Tables. The
duration of patient exposure is most likely minimized with the
use of a probe that is optimized to provide resolution and focal
depth, appropriate to the examination.
Vivid i User's Manual
2378958-100 Rev. 02
The duration of an ultrasound examination is as important
as the acoustic output, since patient exposure to output is
directly related to the exposure time.
Better image quality yields faster clinical results, making it
possible to complete the relevant ultrasound examination
more rapidly. Therefore, any control that improves the
quality of the examination can help to reduce patient
exposure, even though it may not directly affect acoustic
output.
