Abstract

Oppfinnelsen tllvelebringer ikke-lnntrengende undersøkelse av elastisiteten til «ykt biologisk vev for diagnose av fysiologisk og patologisk tilstand i mennesker og dyr, ved & eksitere tangensielle deformasjons-svingnlnger p& overflaten av vevet i frekvensområdet 0.5 til 30 kHz og ved & bestemme hastigheten til den eksiterte overflatebølge som forplanter seg langs den opprinnelige forskyvnings- veKtor. Anordningen for anvendelse av denne fremgangs- måten omfatter en probe ned en sender- og to mottager- piezotransdusere utstyrt ned kontaktspisser og montert på probens legeme ved hjelp av langstrakte rør som tjener som akustiske forsinkelseslinjer. og den elektroniske anordning som former pulser for å eksitere transduseren, utfører behandling av de mottatte akustiske signaler, maler passeringstiden for akustiske pulser fra senderen til mottageren, omformer dem til lydhastighet og viser verdien av hastigheten. Anordningen har også en fasilitet for å standardisere kraften med hvilken proben blir presset mot et vev.
