Stig Synnes and Andrew Gilbert will defend their PhD theses.

Ane presenterer sin masteroppgave The Six Spot Step Test for patients with Multiple Sclerosis onsdag 23. juni.

I høstsemesteret 2021 vil DSB-gruppa gi et nytt kurs i Ultralydavbildning.

Open postdoctoral fellowship in deep learning.

There are open summer job opportunities with our industry partner GE Healthcare:

Antoine Blachet will defend his thesis

Swath sonar: Advanced waveform modulation and associated signal processing techniques

on 21 May. The defense will take place over Zoom, while the trial lecture will be pre-recorded and made available a couple of days beforehand.

Vi søker 2 studenter som kan jobbe 200 timer hver under sommeren 2021.

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 an open PhD position in semi-supervised learning.

We have updated our list of PhD and MSc alumni from our group.

Total Pressure Wavefield Computation for Rough Sea-Surfaces

Bradley Treeby, University College of London 

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.
