A variety of treatment techniques are used with both argon and tunable dye lasers. Each method has its unique advantages: however, all appear to share common limitations such as poor reproducibility, lack of homogeneous energy delivery, and inability to treat rapidly large cutaneous vascular disorders such as port-wine stains. These problems have recently been addressed with a new scanning device designed to automate or speed treatment and provide improved consistency in cosmetic results. Hexascan is a computerized, automated scanning device that allows for the rapid and easily reproducible treatment of large areas of skin using either the dye or argon laser. The scanning pattern is designed to promote uniform energy fluence and minimize unwanted thermal damage to nontarget tissue. Clinical trials using Hexascan with 577 nm and 585 nm wavelengths have shown good results with cutaneous vascular disorders. Utilizing blue-green argon wavelengths, markedly reduced scarring has been observed compared to traditional argon techniques. Use with 514 nm green only argon light has successfully removed a variety of benign brown pigmented cutaneous lesions.
氩激光和可调染料激光都采用了多种治疗技术。每种方法都有其独特的优势：然而，所有方法似乎都存在共同的局限性，如可重复性差、能量传递不均匀，以及无法快速治疗大面积的皮肤血管疾病，如葡萄酒色斑。最近，一种新的扫描设备解决了这些问题，该设备旨在实现治疗自动化或加快治疗速度，并在美容效果上提供更高的一致性。Hexascan是一种计算机化的自动扫描设备，它可以使用染料激光或氩激光对大面积皮肤进行快速且易于重复的治疗。扫描模式旨在促进能量通量均匀，并将对非目标组织的不必要热损伤降至最低。使用Hexascan 577纳米和585纳米波长进行的临床试验表明，对皮肤血管疾病有良好效果。与传统氩激光技术相比，利用蓝绿色氩激光波长观察到疤痕明显减少。仅使用514纳米绿色氩激光已成功去除多种良性棕色色素沉着性皮肤病变。
