1. A detachable and interchangeable transducer module for use in ultrasound treatment, comprising:
a sealed housing comprising an acoustic fluid and an acoustically transparent window,
a circuit board configured for electrical connection to a spring pin connector operably coupled to a hand wand at an interface,
an ultrasonic treatment piezoelectric element configured to focus ultrasound energy at a depth in a range between 3 mm and 9 mm below a skin surface with a treatment frequency in a range of 1 MHz to 10 MHz at an acoustic power in a range of 1 watt to 100 watts,
wherein the ultrasonic treatment piezoelectric element is acoustically coupled to the acoustically transparent window via the acoustic fluid in the sealed housing, and
a movement mechanism comprising a shaft, the movement mechanism configured to attach to an encoder and a stepper motor configured to move the ultrasonic treatment piezoelectric element at a position along the shaft to direct an ultrasonic treatment in a sequence of spaced thermal lesions,
wherein the encoder is configured for measuring the position of the ultrasonic treatment piezoelectric element along the shaft in the sealed housing,
wherein the ultrasonic treatment piezoelectric element is configured to focus the ultrasound energy at the depth for treatment in at least one of the group consisting of: a dermis tissue, a fascia tissue, a muscle tissue, and a fat tissue,
wherein the shaft of the movement mechanism moves the ultrasonic treatment piezoelectric element within the sealed housing;
wherein the transducer module is configured to detach from the hand wand via the interface, which thereby permits a second transducer module to interchangeably attach to the hand wand after detachment from the transducer module.
