Purpose Vessel lumen centerline extraction is important for intraoperative tracking of
abdominal vessels and guidance of endovascular instruments. Three-dimensional …

Purpose Laparoscopic liver resection has significant advantages over open surgery due to
less patient trauma and faster recovery times, yet is difficult for most lesions due to the …

Purpose Registration of pre‐and intraoperative images is a crucial step of surgical liver
navigation, where rigid registration of vessel centerlines is currently commonly used. When …

Fast extraction of blood vessels of abdominal organs is still a challenging task especially in
intra-procedural treatments due to large tissue deformation. In this study, we propose a …

Objective: Two-dimensional fluoroscopy is the standard guidance imaging method for
closed endovascular intervention. However, two-dimensional fluoroscopy lacks depth …

Objective: Computer assisted planning of liver surgery based on preoperative computed
tomography (CT) or magnetic resonance imaging (MRI) data can be an important aid to …

Accurate hepatic vessel segmentation and registration using ultrasound (US) can contribute
to beneficial navigation during hepatic surgery. However, it is challenging due to noise and …

Vessel lumen centerline extraction is an important issue for the intra-operative guidance of
endovascular instruments; furthermore, vessel centerline is often used as a reference …

Abstract Purpose: Registration of Laparoscopic Ultrasound (LUS) to a pre-operative scan
such as Computed Tomography (CT) using blood vessel information has been proposed as …

A method for vessel segmentation and tracking in ultrasound images using Kalman filters is
presented. A modified Star-Kalman algorithm is used to determine vessel contours and …
