A method is disclosed for limiting temperature increase of a treatment area during photodynamic therapy (PDT), whereby temperature sensitive materials in the form of a skin patch or compound are applied over the treatment area. The temperature sensitive materials are optically changing from substantially transmissive to at least one of substantially scattering, absorbing or reflecting at wavelengths used for the PDT, the change occurring upon surpassing a predetermined temperature. In preferred embodiments, the optical changes are reversible as the temperature of the temperature sensitive compounds decrease below a predetermined temperature.
本发明公开了一种在光动力疗法(PDT)过程中限制治疗区域温度升高的方法,即在治疗区域使用皮肤贴片或化合物形式的温度敏感材料。在光动力疗法使用的波长下,温度敏感材料的光学性能从基本透射变为基本散射、吸收或反射中的至少一种,这种变化在超过预定温度时发生。在优选的实施方案中,当温度敏感化合物的温度降低到预定温度以下时,光学变化是可逆的。
