Energy density: 2.5-11J/cm2
When using the Q switch Nd Yag laser tattoo removal machine in treatment, the dose control is for different patients or different parts of the same patient and different treatment stages. The required physical dose (laser energy density) varies greatly. Therefore, the treatment should be based on The biological dose shall prevail. Start with a small dose in a single pulse each time and gradually increase the energy density. At the same time, observe the lesion area until the treatment area turns white and a small amount of bleeding appears after a few minutes. The dose.
After selecting a suitable laser energy density, the laser pulse frequency can be increased (usually 3-5Hz),
To speed up the treatment speed.
The size of the spot can be selected according to the range of the lesion and the energy density required for the treatment, generally 2-4mm is appropriate. When other laser parameters remain unchanged, the smaller the spot, the greater the energy density. After the treatment spot is selected, it is generally fixed during the treatment process, so as not to repeatedly adjust other parameters. Various records should be made during treatment. The future treatment dose can be adjusted with reference to the previous dose and treatment effect. The interval between each treatment is 2-3 months, and the average number of treatments is about 3-6 times.
