Abstract

A targeted UV phototherapy apparatus has a UV radiation source for emitting UV radiation at a first wavelength and a phosphor element separate from the source for converting the UV radiation in the first wavelength to a different UV wavelength in the therapeutic UVB or UVA range. A radiation directing assembly directs radiation from the UV source to the separate phosphor element, and a shaped exit aperture placed directly against a lesion directs radiation emitted from the phosphor element onto a predetermined target area of the lesion.
