1. A device for treating a volume of tissue, comprising:
- a source of EMR configured to transmit EMR to a tissue surface;
a controller electrically connected to said EMR source and configured to provide at least one control signal to said EMR source;
wherein said EMR source is configured to emit at least a first level of flux and a second level of flux in response to said controller, said first and second levels of flux corresponding to first and second penetration depths below the surface of the tissue.

Abstract
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 relieve pain and promote healing of tissue.
