Abstract
An apparatus is provided for irradiating at least a portion of a patient's brain with electromagnetic radiation to treat stroke, Parkinson's Disease, Alzheimer's Disease, or depression. The apparatus includes a source of the electromagnetic radiation. The apparatus further includes an output optical element including a rigid and substantially thermally conductive material and a surface configured to be in thermal communication with the patient's body. The apparatus further includes a cooler thermally coupled to the output optical element to remove heat from the output optical element. The apparatus further includes a heat sink thermally coupled to the cooler, wherein the heat sink is positioned so that the electromagnetic radiation from the source propagates through the heat sink and through the output optical element.
