Acoustic Output Reporting Tables
Vscan – User Manual 8-3
GM092207 02
Explanation of Footnotes
The mechanical and thermal indices may be replaced by one of
the following footnotes because of the reasons listed:
• a: Display of this index is not required for this operating
mode.
• b: This probe is not intended for transcranial or neonatal
cephalic uses.
• c: This formulation for TIS is less than that for an alternate
formulation in this mode.
If so, the table entries are replaced by a “#”, meaning: no data
are provided for this operating condition since the maximum
reported value is not reported for the reason listed.
If neither an index or a footnote is given, this means that the
index is irrelevant for this transducer/mode combination.
