Adding multiple sources

Note

NDK and its examples are under constant development, more information and content will be added to this example soon!

Adding multiple sources for transcranial ultrasound stimulation enables greater precision and control in targeting specific areas of the brain.

By choosing the phase of ultrasound waves for each source, a combined beam can be created that is focused on the desired target precisely. This allows for complex wave patterns that open up new possibilities for therapies.
