If you limit the treatment area, what is the expected behavior of the waves?

Explanation:
Limiting the treatment area reduces the aperture from which the wave energy is emitted. A smaller aperture causes greater diffraction, so the waves spread out more as they travel. This spreading distributes energy over a larger area and lowers the intensity that reaches deeper tissues, so penetration is limited. It won’t stop completely, and it won’t increase energy at the skin; instead, the energy becomes more diffuse and less able to reach deeper targets.
