    • A method and apparatus for determining skin lesion parameters comprise directing light to the skin in which the lesion is located and monitoring the reflection of that light. Then, the spatial and spectral distribution of the reflected light is analyzed. The depth is determined by finding a location where the difference between a spectral intensity of reflected light and an average reflected intensity is greater than a maximal difference between the intensity of each point and an average intensity for normal skin. The wavelength of the light reflected from the location is determined, and from the wavelength the penetration depth is determined. The penetration depth is also the depth of the lesion below the skin surface. The size is determined by determining a plurality of locations where the deviation between the spectral intensity and the average intensity is greater than the maximal deviation for normal skin. Based on the spatial distribution of the locations the size of the lesion is determined.
    • 用于确定皮肤损伤参数的方法和装置包括将光引导到病变位于其中的皮肤并监测该光的反射。 然后,分析反射光的空间和光谱分布。 通过找到反射光的光谱强度和平均反射强度之间的差异大于每个点的强度与正常皮肤的平均强度之间的最大差异的位置来确定深度。 确定从该位置反射的光的波长,并从波长确定穿透深度。 穿透深度也是皮肤表面下方病变的深度。 通过确定光谱强度和平均强度之间的偏差大于正常皮肤的最大偏差的多个位置来确定尺寸。 基于位置的空间分布,确定病变的大小。

    • A method and apparatus for treating skin includes applying pulsed light to the skin to heat and shrinking collagen within the skin, thereby reviving the elasticity of the collagen and of the skin. The epidermis and outer layers of the skin may be protected by cooling with a transparent substance, such as ice or gel, to the skin. The temperature distribution within the skin is controlled by controlling the delay between the time the coolant is applied, and the time the light is applied, by controlling the pulse duration and applying multiple pulses, and by filtering the light and controlling the radiation spectrum, preferably, the spectrum includes light having a wavelength in the range of 600-1200 nm. The pulsed light may be incoherent, such as that produced by a flashlamp, or coherent, such as that produced by a Nd(Yag) laser or a ruby laser, and may be directed to the skin using a flexible or rigid light guide. Also, a method and apparatus for cutaneous resurfacing including directing Er:YAG laser light to the skin. The light may be pulsed, preferably with a delay of about 0.5-10 msec between pulses. In one embodiment the pulses have energy fluences of preferably about 100 J/cm.sup.2.
    • 用于治疗皮肤的方法和装置包括向皮肤施加脉冲光以加热和收缩皮肤内的胶原,从而恢复胶原和皮肤的弹性。 皮肤的表皮和外层可以通过用透明物质(例如冰或凝胶)冷却至皮肤来保护。 皮肤中的温度分布通过控制施加冷却剂的时间和施加光的时间之间的延迟来控制,通过控制脉冲持续时间并施加多个脉冲,并且通过过滤光并控制辐射光谱,优选地 该光谱包括波长在600-1200nm范围内的光。 脉冲光可能是不相干的,例如由闪光灯产生的光,或相干的,例如由Nd(Yag)激光或红宝石激光产生的光,并且可以使用柔性或刚性的光导导向皮肤。 另外,一种用于皮肤表面置换的方法和装置,包括将Er:YAG激光导向皮肤。 光可以是脉冲的,优选在脉冲之间延迟大约0.5-10毫秒。 在一个实施例中,脉冲具有优选约100J / cm 2的能量密度。

    • A method and apparatus for treating psoriasis includes a source of incoherent electromagnetic energy. The energy is directed to a region of tissue to be treated. The pulse duration and the number of pulses may be selected to control treatment parameters such as the heating of healthy tissue and the penetration depth of the energy to optimize the treatment. Also, the radiation may be filtered to control the radiation spectrum and penetration depth. The filtering may include attenuating an UV portion of the radiation spectrum and portions of the spectrum below a desired treatment bandwidth. A light guide for large or small spot sizes may be used to direct the light to the skin. A cooling gel is applied to the skin to be treated in another embodiment. The gel may be cooled either before or after it is applied to the skin.
    • 用于治疗牛皮癣的方法和装置包括非相干电磁能源。 能量被引导到要治疗的组织的区域。 可以选择脉冲持续时间和脉冲数来控制治疗参数,例如加热健康组织和能量的穿透深度以优化治疗。 此外,辐射可以被过滤以控制辐射光谱和穿透深度。 滤波可以包括将辐射光谱的UV部分衰减,并将光谱的部分衰减到期望的处理带宽以下。 可以使用大尺寸或小尺寸的光导来将光引导至皮肤。 在另一个实施方案中,将待冷却的凝胶施用于待治疗的皮肤。 凝胶可以在施用于皮肤之前或之后冷却。
