An accurate diagnosis of burns and pressure ulcers in the early stages can be made by computerized image processing. This study describes a critical assessment of potential methodologies for noninvasive wound evaluation using a color imaging system. We also developed a method for quantifying histological readings and applied these techniques to a porcine(More)
BACKGROUND The transport of particles in surrogate and actual arterial geometries has been investigated synergistically by experimentation and numerical simulation. The motivating application for this work is orbital atherectomy which spawns a particle cloud in the process of debulking plaque from arterial walls. METHODS Paired simulations and experiments(More)
A synergistic investigation involving both experiment and numerical simulation was performed in vitro to determine the heat flow from rechargeable neuromodulation systems into surrounding media. Each system consists of an implant and an external recharging antenna, and the heat flows of each of these components were determined separately. Three systems,(More)
