The feasibility for in vivo navigation of untethered devices or robots is demonstrated with the
control and tracking of a 1.5 mm diameter ferromagnetic bead in the carotid artery of a living …

Changes in vessel wall elasticity may be indicative of vessel pathologies. It is known, for
example, that the presence of plaque stiffens the vascular wall, and that the heterogeneity of its …

PURPOSE: To identify predictors of clinical outcome after arterial embolotherapy for upper
gastrointestinal (UGI) hemorrhage. MATERIALS AND METHODS: Seventy-five consecutive …

Venous malformations are the most common vascular malformations. However, confusion
with respect to terminology and imaging guidelines continues to result in improper diagnosis …

Magnetic tumor targeting with external magnets is a promising method to increase the

The goal of this work is to perform a segmentation of the intimamedia thickness (IMT) of
carotid arteries in view of computing various dynamical properties of that tissue, such as the …

Intravascular ultrasound (IVUS) is a catheter based medical imaging technique particularly
useful for studying atherosclerotic disease. It produces cross-sectional images of blood …
