First, the frequency of 470 kHz was selected, and the CRT resistance probe was performed for deep fat management operation for 10 minutes, and then the CET capacitive mode 470 kHz was selected for superficial fat operation for 6 minutes. Then, select the 940 kHz frequency CET capacitance probe for epidermal tightening operation for 4 minutes. The temperature is set by the energy value. In CRT mode, the energy value is set to 70, and it can reach above 42 ℃ within one minute. In CET mode, the energy value setting is adjusted to 75. The operation mode is to gradually raise the temperature to the midline after partially increasing the temperature at the side of the waist. The technique is mainly to move in a circle and lift to the midline.

Under the condition that the machine is not turned on, the treatment is performed in the same operation time, mode and treatment area of the treatment group.

When operating, first select 470 kHz frequency, CRT resistance probe for deep fat management operation for 10 minutes, and then select CET capacitance mode 470 kHz for superficial fat operation for 6 minutes.

Ultrasound (GE LogiQ P6 ultrasound system, 132 GE Healthcare, Wauwatosa, WI) was used to measure the height of abdominal subcutaneous adipose tissue at four positions below the left and right abdomen three times respectively. A mold plate was designed to fix the ultrasound probe, centered on the umbilicus, and symmetrically symmetrically. Areas A and B are horizontal measurement of ultrasonic probe, which are located above and below the left/right abdomen respectively, and areas C and D are vertical measurement of ultrasonic probe, which are located outside and inside respectively.Each measurement site was divided into three measurements and the average value was taken, and the overall average value of the three averages of each site was taken as the final value.
