Vessels and Blood Flow from Ultrasound Åsmund Birkeland
Vessel Extraction from Ultrasound • Ultrasound Painting of Vascular Tree [VMV2010] • Quickly extract 3D models live during examination • Minimize interaction • Using basic 2D B-mode ultrasound + tracking
Challenges • Holes in the surface • Surface artifacts • Tracking calibration • Motion compensation
New Vessel Geometry • Implicit surfaces from points and tangents • Smooth • Hole-free • Cooperation with IMPA, Brazil [Ives Macedo 2011]
New Data • New 4D ultrasound streaming (Dag Magne Ulvang) • Volume registration (Ola Kristoffer Øye)
Live 3D Blood Flow • Input: 3D vascular structure and Doppler data • Illustrative depiction of 3D flow on vessel geometry • Environments • Flow phantom • Carotid artery • Hepatic/portal vascular tree
