1. An aesthetic imaging and processing system for simultaneously focusing a plurality of spaced apart thermal condensation points from a single ultrasound transducer for cosmetic treatment, the system comprising:

  • an ultrasound probe configured for ultrasound imaging and ultrasound processing of tissue at a plurality of locations at one or more focal depths, the ultrasound probe comprising;

    a single ultrasound transducer module configured for coupling to the ultrasound probe,wherein the single ultrasound transducer module includes a single ultrasound transducer configured to apply sonication producing a plurality of spaced apart thermal condensation points to tissue at the plurality of locations at the one or more focal depths with at least one of a group including amplitude modulation, polarization, and phase shift,wherein the single ultrasound transducer is configured to produce a simultaneous plurality of spaced apart thermal condensation points in tissue by application of therapeutic ultrasound,a first switch operable to control an ultrasound imaging function so as to provide ultrasound imaging;

    a second switch operable to control a sonication function so as to provide the sonication; and

    a movement mechanism configured to direct sonication in at least one sequence of individual thermal cosmetic treatment zones;

    wherein the single ultrasonic transducer module is configured to be operably coupled to at least one of the first switch, the second switch, and the movement mechanism;

    a control module, said control module comprising a processor, anA display including a graphical user interface for controlling the single ultrasound transducer module,wherein the single transducer module contains a single piezoelectric element, wherein portions of the single piezoelectric element are configured to produce a plurality of corresponding piezoelectric element changes in response to an electric field applied to the single transducer module,wherein the polarization comprises different polarization moments provided from multiple portions of the single piezoelectric element,wherein the phase shifts of the multiple portions of the single piezoelectric element are excited by corresponding signals applied to the multiple portions of the single piezoelectric element at different phases.
