Physikalische Parameter extrakorporaler Stoßwellen Physical Parameters of Extracorporeal Shock Waves
نویسندگان
چکیده
Zur Evaluierung des Wirkmechanismus, der Vergleichbarkeit unterschiedlicher StoßwellenqueUen und zur Erstellung von Therapiestandards der ESWT (Extracorporale Stoßwellentherapie) ist die meßtechnische Erfassung und Kenntnis der physikalischen Parameter Voraussetzung. Die genauesten Meßergebnisse werden mit Glasfaserhydrophonen erzielt. Einer typischen Schalldruckkurve können somit verschiedene Einzelparameter (Amplitude, Druckanstiegszeit, Unterdruckphase, Pulsbreite) entnommen werden, aus denen Energieflußdichte, Fokusausdehnung und -volumina sowie Fokusenergie, effektive Energie im definierten Areal und effektive biologische Energie berechnet werden können. Mit Hilfe der dargestellten Parameter läßt sich ein theoretisches Behandlungsprotokoll erarbeiten.

Experimental observation of azimuthal shock waves on nonlinear acoustical vortices
Thanks to a new focused array of piezoelectric transducers, experimental results are reported here to evidence helical acoustical shock waves resulting from the nonlinear propagation of acoustical vortices (AVs). These shock waves have a three-dimensional spiral shape, from which both the longitudinal and azimuthal components are studied. The inverse filter technique used to synthesize AVs allo...
متن کاملA comparative review of extracorporeal shock wave generation.
Shock waves are specific sound waves produced by shock-wave generators; the generators currently available have different physical properties and represent different technical solutions. The measurement of shock-wave pressure is necessary in laboratory settings to define the physical characteristics of a given shock-wave source. Under clinical conditions other variables, e.g. the stone-free rat...
