Results
Most relevant correlations were as follows:
- energy-SS,
negative.
This indicates that patients with a lower skull score,
i.e.
lower skull density ratio,
need to be delivered more energy in order to obtain optimal results.
- Time-temperature,
negative.
- Time-SS,
negative.
In patients with lower skull density ratio,
more time must be allowed to the machine for energy supply in order to obtain an optimal result.
- Time-elements,
negative.
If few tranducers are available (e.g.,
if there are many intracranial calcifications,
or if the helmet in angled in certain ways),
more time is required to deliver an amount of energy.
- Temperature-SS,
positive.
When skull density ratio was higher,
it was also easier to obtain high sonication temperatures.
- Elements-temperature,
positive.
- Elements-skull area,
positive.
More elements were available in patients with a bigger skull.
