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.

The PhD included development of 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 3D frame on typical computer hardware as of 2008.


Examples of automatic 3D segmentation/tracking conducted in real-time:
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.
