Radiation delivery module and dermal tissue treatment method

摘要

A radiation delivery module (8) includes a body (48) supportable on a patient's skin and defines a skin surface plane generally aligned with the patient's skin surface (40). A radiation source (22) is mounted to the body and produces a beam (34) of tissue-damaging radiation directed transverse to and at the skin surface plane. The radiation beam creates a radiation spot (42) having a length (36) and a width (44) at the skin surface plane, the length being at least about 5 to 10 times the width. A number of scanned diode laser radiation sub-sources (64) each directing a radiation beam component (66) at the radiation spot may be used. The radiation source may include a rod lens as a focusing optical element. The radiation delivery module may also include a radiation source translator (18) so that the radiation spot moves in a direction generally perpendicular to the length of the radiation spot.
