THE INVENTION DISCLOSES AN ULTRASONIC FAT REDUCTION AND BODY SHAPING MACHINE THAT INCLUDES A TREATMENT HEAD (1), A WAVE SOURCE CARRYING APPARATUS (15), A MECHANICAL ARM (2), A TREATMENT BED, A LIFT CYLINDER BODY, A TOUCH SCREEN (6) AND CONTROL CIRCUITS (8). A MENU FOR USER SELECTION OPERATION IS PROVIDED ON THE TOUCH SCREEN (6). THE TREATMENT HEAD (1) IS CLAMPED IN THE WAVE SOURCE CARRYING APPARATUS (15 S AS TO BE FIXEDLY CONNECTED TO THE MECHANICAL ARM (2) AS A WHOLE. THE MECHANICAL ARM (2) IS FIXEDLY CONNECTED TO THE LIFT CYLINDER BODY THAT IS FASTENED ON THE TREATMENT BED-BASE (5) THE INVENTION IS TO PROVIDE AN ULTRASONIC FAT REDUCTION AND BODY SHAPING MACHINE THAT FACILITATES ASSEMBLING AND DISASSEMBLING OF A TREATMENT HEAD, ELEVATES AND DESCENDS A MECHANICAL ARM FREELY. THE ULTRASONIC FAT REDUCTION AND BODY SHAPING MACHINE HAS AN ULTRASONIC FREQUENCY OF 1 MHZ TO 3 MHZ USING AN ULTRASONIC EMISSION MODE WITH HIGH INTENSITY, NARROW PULSE WIDTH AND LOW DUTY CYCLE.
