摘　　要：根据鲜红斑痣的病理特点,建立分层模型中包含分立血管的皮肤模型,以血管为主要研究对象,用蒙特卡罗的模拟方法模拟在强脉冲光系统治疗鲜红斑痣中,血管中光能量密度的分布规律。结果显示与单波长激光相比,强脉冲光照射下血管中光能量的分布更加均匀,在光束传输方向上能量梯度更平坦;且血管中能量极大值更小。According to the pathological features of port-wine stains, we established the multi-layer skin model embedded with discrete blood vessels, use the Monte-Carlo algorithm to simulate the regularities of optical energy density distri- bution of blood vessels in intense pulsed light treatment of port-wine stains. The results showed that, compared with single-wavelength laser, the light energy distribution in intense pulsed light treatment is more uniform, in the beam propagation direction, the energy gradient is more flat, and the maximum energy of the blood vessels is smaller.
