CO2激光换肤术是非常准确的，但它并不是没有疤痕等并发症。本研究的目的是评估从皮肤层发出的红外（IR）辐射的模式，并使用此模式来区分这些层之间的换肤。使用CO2表面置换激光（Sharplan SilkTouch）进行皮肤去上皮化。一根银光纤将在换肤过程中从皮肤发出的辐射传递到IR光子检测器。从皮肤层发出的信号的时间依赖性曲线进行了统计学评估，并显示表皮和真皮层之间的显着差异。在体内和离体测量期间获得了类似的结果。皮肤层发射之间的差异可用于激光表面重塑期间的深度导航。
CO2 laser resurfacing is very accurate, but it is not free of complications such as scarring. The objectives of the present study were to evaluate the pattern of the infrared (IR) radiation emitted from skin layers and to use this pattern to distinguish between these layers during resurfacing. A CO2-resurfacing laser (Sharplan SilkTouch) was used for the de-epithelialisation of skin. A silver halide optical fibre delivered the radiation emitted from the skin during resurfacing to an IR photonic detector. Time-dependent curves of the signals emitted from the skin layers were statistically evaluated and showed significant differences between the epidermis and the dermal layers. Similar results were obtained during in-vivo and ex-vivo measurements. The difference between the skin layers emission may be used for depth navigation during laser resurfacing.
