tailieunhanh - GLOBAL VIEW OF HIV INFECTION

Techniques for non-invasive Breslow determination use either mechanical or electromagnetic waves. A wave is the propagation of a perturbation inducing reversible variations of local physical properties. It transports energy but no matter. Ultrasounds and optical waves are used mainly because of their innocuousness. In the next paragraphs, ultrasonography then several optical techniques will be developed. Basic physical principles of each type of wave interaction with skin will be described then accuracy of Breslow index determination by such techniques will be given. One paragraph will talk about techniques that have already given promising results in a clinical environment in vivo, namely ultrasonography and dermoscopy | GLOBAL VIEW OF HIV INFECTION Edited by Vishwanath Venketaraman Global View of HIV Infection Edited by Vishwanath Venketaraman Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2011 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which permits to copy distribute transmit and adapt the work in any medium so long as the original work is properly cited.
