Abstract
A method and system of delivering energy to material in which energy is converted to thermal energy in the material, and prior to significant therapeutic or other physiological change in a selected or target region of the material, results in a temperature rise which is maximum in a selected region of the material but which is insufficient to cause significant therapeutic or other physiological effect, the system for selective preheating of subsurface target regions of material such as human tissue including an energy source to preheat the material or tissue, a passive or active cooling means, and a device for delivering therapeutic or treatment energy, such as pulsed, electromagnetic, laser or non-coherent energy, to tissue during or after the preheating and cooling of the tissue.
