Abstract

A non-invasive variable depth ultrasound treatment method and system comprises a variable depth transducer system configured for providing ultrasound treatment to a patient. An exemplary variable depth transducer system can comprise a transducer configured to provide treatment to more than one region of interest, such as between a deep treatment region of interest and a superficial region of interest, and/or a subcutaneous region of interest. The variable depth transducer can comprise a transduction element having a piezoelectrically active layer, matching layers and/or other materials for generating radiation or acoustical energy. The variable depth transducer may be configured to operate at moderate frequencies within the range from approximately 750 kHz to 20 MHz or more. In addition, the transduction element may be configured with a variable depth device comprising one or more materials configured to allow for control and focusing/defocusing of the acoustic energy to more than one region of interest.
