Abstract

Kontrastmidler til ultralydavbilding som inneholder to eller flere typer gassinneholdende mikropartikler som har forskjellig følsomhet overfor ultralydtrykk. Mikropartikkeltyper med' relativt lav følsomhet overfor ultralydtrykk gir en respons på høy akustisk energi i nærfeltet der mikropartikkeltyper med relativt høy følsomhet har lett for å bli ødelagt. Mikropartikkeltyper med høyere følsomhet er effektive i fjernfeltets miljø med lavere akustisk energi, der mikropartikkeltyper med lavere følsomhet ikke gir særlig respons.
