Background and Objectives: Hypervascular skin lesions (HVSL) are treated with medical lasers characterized by a variety of parameters such as wavelength λ, pulse duration tp, and radiant exposure E that can be adjusted for different pathology and bl

We report on application of pulsed photothermal radiometry (PPTR) to determine the depth of port wine stain (PWS) blood vessels in human skin. When blood vessels are deep in the PWS skin (>100 μm), conventional PPTR depth profiling can be used to de

Infrared measurements have been used to profile or image biological tissue, including human skin. Usually, analysis of such measurements has assumed that infrared absorption is due to water and collagen. Such an assumption may be reasonable for soft

We designed a photoacoustic probe to determine the depths of epidermal melanin layer and port wine stain (PWS) in human skin. We present experimental data showing limitations in its use. We developed acrylamide tissue phantoms with optical properties
