Devices and methods for utilizing electromagnetic radiation and other forms of energy to treat a volume of tissue at depth are described. In one aspect, a device modulates the flux incident on surface tissue to control and vary the depth in the tissue at which an effective dose of radiant energy is delivered and, thereby, treat a specific volume of tissue. The methods and devices disclosed are used to perform various treatments, including treatments to prevent and relieve pain and promote healing of tissue. |
