3D Vector Flow Imaging

Medical ultrasound imaging is widely used for studying blood flow dynamics in the human circulatory system. However, blood velocity estimates using conventional techniques are angle dependent. This strongly limits the possibility of visualizing complicated flow patterns and obtaining the true velocity. This problem has been remedied by methods developed at Center for Fast Ultrasound Imaging (CFU) at DTU Elektro for 2D velocity estimation.

The aim of this project is to develop a method for full 3D vector velocity imaging to correctly show the velocity vector.  Methods for acquiring data and estimating the velocity are developed based on 2D techniques already developed at CFU with main focus on the transverse oscillation method. The methods will then be implemented on the experimental ultrasound scanner SARUS at CFU and evaluated on flow phantoms and human volunteers.

With 3D vector flow imaging, complex flow patterns can be visualized and, potentially, pathological flow patterns around occlusions, valves, and bifurcations can be identified.

About Michael

Michael is 27 years old and has a Master in Medicine and Technology from 2009. During his master years, Michael spent seven months at Duke University in North Carolina.

About his current activities, Michael explains: I am simulating blood flow in 3D and estimating the velocity using an ultrasound simulation tool named Field II. The results are promising. I have also just finished writing a report for BK Medical describing my recent results. 

Michael’s project is expected to finish in 2012. He has not yet decided whether he would like to stay in the academic world or try out the industry.
