Abstract
Methods, systems, devices, and computer program products include positioning single-use radiation sensor patches that have adhesive means onto the skin of a patient to evaluate the radiation dose delivered during a treatment session. The sensor patches are configured to be minimally obtrusive and operate without the use of externally extending power cords or lead wires.
