Abstract
An apparatus and method of use for a comprehensive transcranial low-level light therapy for use with ischemic brain tissue using a multitude of polychromatic Light Emitting Diodes (LEDs) embedded into a flexible head covering that stretches securely around the patient's cranium to bath the entire cranium cavity in a variable frequency, variable power density light spectrum, maximizing all beneficial effects to the cellular tissues whether or not they are specifically deprived of blood from the ischemic stroke event. The bulbs covering the n-p junction of the semiconductor LEDs directly contact the patient's cranial skin to maximize the depth of penetration of the wavelengths into the brain's cortex cells. By using many individual point-source LEDs emitting all around the cranium, greater therapeutic benefit can be achieved as more of the cortex tissues are irradiated.
