Cet article decrit succinctement les differents types de generateurs d'ondes de choc utilises en lithotritie. Les ondes de choc ne sont pas sans effet sur les tissus. Cette propriete peut etre appreciee comme un effet deletere lors du traitement des calculs renaux, mais peut titre mise a profit pour d'autres applications de therapie.
The actual interaction mechanisms of stress shock waves with renal calculi or gall bladder stones during disintegration, noninvasively, are still not understood clearly. The high-pressure shock waves create transient cavitation that is accepted as one behind the mechanisms of disintegration of those stones. The cavitation phenomenon and other associated mechanisms responsible for the disintegration...
Le systeme d'analyse cinematique ZEBRIS CMS-HS calcule, en temps reel, les coordonnees tridimensionnelles de marqueurs cinematiques en utilisant le principe de la triangulation ultrasonore. Cependant, la propagation des ondes ultrasonores peut etre alteree par des facteurs exterieurs tels que les reflexions du signal, le vent, les variations de temperature. Pour chacune de ces conditions, les coordonnees...
