Hyperspectral imaging, image analysis and diffusion theory were used to visualize skin vasculature and to monitor the development of fresh skin bruises. Bruises were inflicted in a porcine model, and the development of the hemorrhage was monitored us

Intravascular thermography has been proposed as a method for detecting vulnerable plaque. A marker of vulnerability in a plaque is inflammation, which is believed to reduce its mechanical stability. It has been hypothesized that this inflammation lea

Background and Objective Bruises are currently evaluated by visual inspection, and little is known about the first phase after injury. The temporal development of fresh injuries must be accurately described to be able to age bruises in a reliable man

Background and Objectives Aging of injuries on a victim's body is an important aspect of forensic medicine. Currently, visual assessment and colorimetry based on empirical criteria are the most common techniques for this task, although the results ar

A comparative study of photoacoustic and reflectance methods for determination of epidermal melanin content. Journal of Investigative Dermatology, 122(6), 1432-1439. doi: 10.1111/j.0022-202X.2004.22610.x. UC Irvine: Retrieved from: http://www.escholarship.org/uc/item/2vh7z2bk

Although epidermal melanin content has been quantified non-invasively using visible reflectance spectroscopy (VRS), there is currently no way to determine melanin distribution in the epidermis. We have developed a photoacoustic probe that uses a Q-sw
