Abstract

An illumination system (1) for photodynamic therapy is provided, the illumination system comprising an illumination source (2), which is configured to emit an electromagnetic radiation (3) to illuminate a target surface (4) during operation, and an electronic control unit (5), wherein the illumination source is configured such that the intensity of the electromagnetic radiation emitted by the illumination source can be varied, wherein the electronic control unit is operatively connected to the illumination source and configured to control operation of the illumination source according to an illumination protocol during an illumination session performed with the illumination system, and wherein the illumination protocol comprises instructions to operate the illumination source during the illumination session in a plurality of different modes, the modes comprising: a) a first mode, wherein, in the first mode, the electronic control unit controls operation of the illumination source such that the intensity of the electromagnetic radiation emitted by the illumination source is increased continuously or quasi-continuously from a base intensity B to a target intensity T within a first mo…
