Anne Saris Blood velocity vector imaging in the carotid artery using ultrasoundA stroke is a major cause of death and disability. A substantial part of all strokes is caused by the rupture of an atherosclerotic plaque in the carotid artery. Current diagnosis and treatment are mainly based on the amount of narrowing, which is inadequate. In only one out of six patients with a severe stenoses, surgery prevents a stroke. While some patients with moderate stenosis, who are treated with medication only, experience a stroke which might had been prevented with surgery. This means patients are over- and under-treated. The process of atherosclerosis is associated with changes in the blood flow. Therefore, obtaining information about the blood velocities could result in improved diagnosis and risk stratification. An ultrasound technique has been developed to accurately quantify the blood velocities in the carotid artery. This technique was validated using simulations and experiments. And finally, the method was applied in healthy volunteers and patients.

Anne Saris (1987) studied Medical Engineering at the Technical University of Eindhoven and obtained her Master’s degree in 2012. The research is this thesis was performed at the Medical Ultrasound Imaging Center (MUSIC) which is part of the department of Radiology and Nuclear Medicine at the Radboud university medical center. Currently, Anne is a postdoctoral researcher focusing on blood flow imaging in 3D using ultrasound.
