Project Title: Vector flow imaging for angle independent flow estimation in the heart
Group:Center for Fast Ultrasound Imaging
Supervisors:Jørgen Arendt Jensen (DTU), Jesper James Linde (Rigshospitalet), Christian Hassager (Rigshospitalet)   

Project Description: 
In this project I will be trying to estimate the blood flow velocity in the human

heart in 2D using data from regular ultrasound scans. The data will then be processed so that we can extract blood flow velocities in axial and lateral directions regardless of the angle between the ultrasound beam and the flow direction. This study involves both healthy participants and patients with structural heart disease.

Perspective:

Conventional ultrasound scanners are only able to estimate velocities up to a certain value, based on the transducer’s center frequency. Also, this velocity can only be measured when the flow direction is parallel to the ultrasound beam. In this project, we try to prove that our method can estimate velocities higher than those measured in the conventional methods and also that this estimation is independent of the beam-flow angle.

physics at the University of Cyprus. He acquired his Master’s diploma in Medical Physics,
specializing at MRI imaging, at the University of Copenhagen and is now doing his PhD at
DTU in cardiac ultrasound imaging.
