MSc in computer science and PhD in medical imaging from IDI and ISB at NTNU (Trondheim, Norway).
Currently working as R&D engineer for GE Vingmed Ultrasound (GE Healthcare), Oslo, Norway.
Have completed a PhD on algorithms for real-time tracking of deformable models in volumetric data, using sequential state estimation. The primary application was automatic left ventricular segmentation in 3D echocardiography.
As part of my PhD, I developed the world's fastest algorithm for 3D segmentation and tracking with deformable models. The developed tracking framework operated 10-100 times faster than known comparable systems, with typical execution times of 5 ms per model per frame on standard computer hardware.
Examples of automatic 3D segmentation/tracking conducted in
Endocardial LV segmentation with a Doo-Sabin surface.
Endocardial and epicardial LV segmentation with two coupled Doo-Sabin surfaces.
Tracking of LV endo+epi and RV in cardiac CT.
Automatic bladder segmentation.
