Abstract
An apparatus and method, for selective thermal treatment of tissue, below the surface, while avoiding injury to the superficial layers of the tissue. The apparatus comprises a reflective beam conversion system for providing a pre-selected therapeutic dose of light energy of optimal spectrum and optimal pulse duration to a confined target volumes at predetermined depth under the tissue surface, while reducing the thermal exposure of the surface of the tissue, and the overlying and surrounding tissues. The method is advantageous for treating a variety of medical and dermatological conditions in a safer and more effective manner.

Apparatus for delivering radiation beneath a tissue surface, comprising:
- a radiation source for inputting a beam of said radiation of predetermined energy fluence;
- and
- a beam converter having a symmetry axis, said beam converter adapted to direct said input radiation in a plurality of directions spaced around said symmetry axis and inclined angularly to said symmetry axis, towards at least one target volume disposed on said symmetry axis beneath said surface, wherein
- said radiation has an energy fluence at said surface which is lower on said axis than the maximum energy fluence of said radiation on said surface,
- said energy fluence of said radiation at said surface is lower than said predetermined energy fluence of said input beam, and
- said energy fluence of said radiation at said at least one target volume is higher than said energy fluence of said radiation at said surface.
