Abstract
A device for applying light in photodynamic therapy is arranged to apply light in a pattern corresponding to the configuration of the lesion to be treated. The device may be customized in response to an image of the patient acquired before treatment. Alternatively, the device may include sensors for detecting a characteristic of tissue overlying each region of the device so that the device either emits light or does not emit light in each region depending upon the characteristics of the overlying tissue.
