Fagfelt/arbeidsområde
Forskning innen medisinsk ultralydavbildning med hovedvekt på blodstrømsavbildning av hjertet. Ny teknologi gjør det stadig mulig å forbedre visualisering av blodstrøm i både 2D og 3D, og bedre og mer informasjon om blodstrømningen i hjertet kan hjelpe legene til å stille sikrere diagnoser og gi rett behandling og oppfølging av pasientene.
Del av ultralydgruppen på Institutt for sirkulasjon og bildediagnostikk.
