SYSTEM AND METHOD FOR DERMATOLOGICAL TREATMENT GAS DISCHARGE LAMP WITH CONTROLLABLE CURRENT DENSITY

摘要

A system and method using a gas discharge to provide for dermatological treatments, such as hair removal. The system provides for varying the spectral output of the gas discharge lamp by varying the current density through the lamp. This ability to control the spectral output is particularly beneficial where the a variety of different skin types and hair types are being treated for hair removal. By changing the current density through the lamp, the spectral output from the lamp can be changed. Thus, where a power supply provides the ability to control the amount of current density through the lamp, the spectral output from the lamp is controlled and selected for a particular skin type being treated.

1. A method of treating the skin of a patient using a handpiece including a flashlamp and a cooled window for contacting the skin and through which treatment radiation generated by the flashlamp is transmitted to the skin, said method comprising the steps of:
selectively driving the gas discharge lamp with one of a first or second current density such that the gas discharge lamp outputs therapeutic electromagnetic radiation having one of a first or second spectral profile and wherein the first current density is higher than the second current density so that the first spectral profile has more energy distributed at shorter wavelengths than the second spectral profile; and transmitting one of the first or second therapeutic electromagnetic radiation outputs from the gas discharge lamp through the cooled window and wherein the temperature of the window is selected based on whether the first or second current density is selected.
