Abstract
A method and apparatus are provided for performing a therapeutic treatment on a patient'"'"'s skin by concentrating applied radiation of at least one selected wavelength at a plurality of selected, three-dimensionally located, treatment portions, which treatment portions are within non-treatment portions. The ratio of treatment portions to the total volume may vary from 0.1% to 90%, but is preferably less than 50%. Various techniques, including wavelength, may be utilized to control the depth to which radiation is concentrated and suitable optical systems may be provided to concentrate applied radiation in parallel or in series for selected combinations of one or more treatment portions.

2. Apparatus for performing a treatment on a volume located at area and depth coordinates of a patient'"'"'s skin including:
-
a source of treatment radiation; a mechanism which cools the patient'"'"'s skin over said area coordinate to a selected temperature; controls for selectively operating said mechanism to at least one of precool said skin for a selected duration before application of radiation and during application of radiation, said mechanism and controls cooling to a temperature and for a duration sufficient to cool said skin to at least a selected temperature below normal body temperature to at least a depth below said depth coordinate; and an optical system including multiple foci to which treatment radiation from said source is selectively applied, said optical system concentrating said treatment radiation to a depth in said volume and to selected areas of said volume to define treatment portions, said treatment portions being less than said total volume, each said portion being substantially surrounded by untreated and cooled skin, said optical system further comprising a controller for successively directing said radiation to said multiple foci. - View Dependent Claims (3)

21. A method of treating a volume of a patient'"'"'s skin by irradiating portions of the volume, comprising:
irradiating by treatment radiation a plurality of spatially separated three-dimensional portions within a volume of the skin requiring treatment for a dermatological condition such that following application of the treatment radiation each irradiated portion is surrounded by a non-irradiated portion, wherein said irradiated portions comprise a fraction of said volume in a range of about 10% to about 30%.
-
22. A method of treating a volume of a patient'"'"'s skin by irradiating portions of the volume, comprising
providing a source of treatment radiation, directing treatment radiation from said source to a plurality of spatially separated three-dimensional treatment portions disposed in a selected volume of the patient'"'"'s tissue requiring treatment such that different treatment portions are irradiated sequentially over time such that following application of the treatment radiation each treatment portion is surrounded by an untreated portion of said volume, wherein said treatment portions comprise a fraction of said volume ranging from about 10% to about 50%.
-
24. A method of treating a selected volume of a patient'"'"'s skin by irradiating portions of the volume, comprising:
-
providing a source for generating treatment radiation, and focusing said treatment radiation sequentially over time onto selected treatment regions within said volume such that following application of the treatment radiation each treatment region is separated from other treatment regions by untreated tissue within said volume. - View Dependent Claims (25, 26, 27, 28)
