System and method for ultrasound treatment

A hand wand for use in ultrasound treatment, comprising:

• a handle;
• a button operably controlling an ultrasound treatment function;
• a movement mechanism;
• an integrated receptacle comprising a spring pin connector, and
• a removable transducer module comprising:
• a circuit board configured for electrical connection to the spring pin connector operably coupled to the hand wand at the integrated receptacle,
• a sealed housing comprising an acoustic fluid and an acoustically transparent window, and
• an ultrasonic treatment piezoelectric element contained within the sealed housing, the ultrasonic treatment piezoelectric element being is configured for acoustic coupling to the acoustically transparent window via the acoustic fluid,
• wherein the ultrasonic treatment piezoelectric element is configured to focus ultrasound in a linear sequence of individual thermal lesions 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 movement mechanism comprises a stepper motor configured to move the ultrasonic treatment piezoelectric element inside the removable transducer module along a shaft when the removable transducer module is coupled to the integrated receptacle,
• wherein the movement mechanism further comprises an encoder provided along the shaft, the encoder being configured to measure a position of the ultrasonic treatment piezoelectric element along the shaft in the sealed housing.
