WARNING
Unintended heating of healthy bone marrow cannot be observed due to its high fat content.
Use sufficient safety margins when planning sonications of those areas that need to be
protected from excessive heating. Failure to do so may cause tissue damage in unintended
regions.
WARNING
Multiple treatments of the same volume may increase the risk of heat buildup, potentially
resulting in unpredictable tissue damage outside the planned cell. It is not recommended to
sonicate the same volume of tissue more than once.
6.8.7. Reviewing the sonication results during the cooling time
1.
On the Analysis tab, check that the sonication time and the maximum temperature were at an
acceptable level. After a successful sonication also check the recommended power to optimize the
power for the next sonication.
2.
Review the temperature maps to check that no unwanted heat buildup occurred in the near field
or far field. Usually you can see some colored pixels outside the heated area. For more
information, see 4.6.1. Misplaced heating or motion artefact?.
3.
If you want to analyze signs of near-field heating in more detail, use either of:
-
The Pixel Info tool.
-
The Profile Line tool, to display a temperature profile in the Temperature Curve on the
Analysis tab.
The temperature should not exceed 47 °C (117 °F) in the near-field monitor slice. If you repeatedly
observe high temperatures in the abdominal muscle, do not continue the treatment.
The tool buttons for Pixel Info and Profile Line are hidden by default, but you can add them to the
toolbar from the Tools → Toolbar Options menu.
