1. A method of photodynamically diagnosing or treating a patient, the method comprising:
applying 5-aminolevulinic acid (ALA) to a treatment surface on an extremity of the patient,
illuminating, by an illuminator comprising a plurality of light sources disposed on surfaces of a plurality of panels, the treatment surface of the patient;
wherein the plurality of panels are connected by hinged structures on inner side surfaces of adjacent panels, wherein the illuminator is configured to uniformly illuminate the treatment surface via the light sources;
positioning one of the plurality of panels as a center panel to face the treatment surface; and
positioning two or more of the plurality of panels to be extended from the center panel such that the plurality of panels are positioned to allow treatment of the extremities of the patient;
wherein each of the plurality of panels has two first edges and two second edges shorter than the two first edges, and the light sources are arranged such that a higher intensity of light is emitted proximate the second edges compared to the intensity of light emitted not proximate the second edges.
