1. A non-invasive ultrasound treatment system for providing treatment to a patient, the non-invasive ultrasound treatment system comprising:

  • a variable depth transducer comprising a transduction element and a variable depth element, the variable depth transducer operable to provide non-invasive treatment to tissue at least two depths in a patient, the transduction element comprising at least one surface configured to emit acoustic energy, the variable depth element comprising a frequency dependent device configured for spatial control of a focal depth and position of the treatment to the tissue by changing a frequency of the acoustic energy emitted by the at least one surface of the transduction element; and

    a controller in communication with the variable depth transducer, the controller comprising a control of the spatial control and a control of a frequency range of the acoustic energy.
