Prosjektet har fokus på utvikling relatert til integrasjon av databeregninger i det nye kurset Ultralydavbilding (IN3015/IN4015). Her inngår for eksempel å tilrettelegge for at kursets deltakere får mer konkret hands-on-erfaring i signalbehandling, datavisualisering, og simulering av bølgeforplanting samt hvordan dette integreres i ultralydavbildningssystemer med spesielt fokus på medisinske applikasjoner.
Vi vill i stor grad bruke prosesseringsplattformen UltraSound Toolbox i dette arbeid https://www.ustb.no/
We have two PhD positions open in signal processing and acoustic beamforming / sonar. Application deadline 28 February:
Kaja F. Kvåle will be defending her thesis Detection of mechanical waves in the left ventricle using high frame rate imaging on October 13.
Pleases read this news item on the Department web for information on how to join the fully digital defense and trial lecture.

The accurate simulation of wave propagation in tissue realistic media has many applications in ultrasonics and photoacoustics. In this talk, I will give an overview of the open-source k-Wave Toolbox and it's application to time-domain simulations. The governing equations and numerical methods will be introduced, including the use of spatial fractional derivatives to account for acoustic absorption. Finally, I will discuss applications of the models in photoacoustic image reconstruction and exposimetry for high-intensity focused ultrasound.
