狭义的超声治疗器,其频率为800KC~1Mc/s,其振动发射面直径为30mm,超声强度为1~3W/cm~2左右,最高达5W/cm~2。聚焦超声波的发射方向是随透镜而发生改变,利用其产生的焦点,作用于特定部位,可产生强有力的破坏作用;是为广义的超声波疗法。现今,实际应用的超声波频率为500kc-5mc/s,而主要应用1mc/s 左右,(在机体组织中其波长为1.5mm)。应用时在超声波焦点处的超声强度与作用时间;最大强度为500W~2KW/cm~2,而作用时
Narrow sense of the ultrasound device, the frequency of 800KC ~ 1Mc / s, the vibration emission surface diameter of 30mm, ultrasound intensity of about 1 ~ 3W / cm ~ 2, up to 5W / cm ~ 2. Focused ultrasound emission direction is changed with the lens, the use of its focus, acting on a specific site, can have a strong destructive effect; is a generalized ultrasound therapy. Today, the practical application of the ultrasonic frequency of 500kc-5mc / s, while the main application of about 1mc / s, (in the body tissue wavelength of 1.5mm). Ultrasonic intensity and duration of application at the focal point of ultrasound; maximum intensity 500W ~ 2KW / cm ~ 2, while the role
