Bakgrunn og aktiviteter
Mine interesser og forskning er innen medisinsk ultralydavbildning, en metode hvor man basert på ekko fra utsendte høyfrekvente lydbølger danner bilder og måler egenskaper til vev og blod i kroppen. Ultralydavbildningsteknologien har hatt en rivende utvikling de siste årene, og mulighetene for klarere bilder som kan gi en sikrere medisinsk diagnose blir stadig forbedret.
