Lasse Thurmann Jørgensen, Postdoc

PhD

The PhD project title was "3D motion estimation." The objective was to develop viable methods for 3D ultrasound velocity estimation, a challenge because 3D ultrasound imaging requires significant data reduction and image optimization.

 In this project, the data reduction was achieved using a row-column addressed array (RCA) probe, which acquires the 3D signal at a much lower data rate (roughly the square root of the data rate typically required).

 During the project, it was demonstrated that the RCA probe could capture blood's 3D velocity vector field in real time over a large volume.

 A new 3D imaging algorithm was also developed for the RCA probe, which speeds up image processing by approximately two orders of magnitude. The new imaging method can process thousands of image volumes per second, enabling real-time 3D vector flow imaging with a single computer graphics card.
