  1. 1. Performance Evaluation of Lumen Segmentation in Ultrasound Images

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Alexander Kadeby; [2023]
    Keywords : Image Segmentation; Atherosclerosis; VIPVIZA; Lumen Segmentation; Threshold Algorithms;

    Abstract : Automatic segmentation of the lumen of carotid arteries in ultrasound images is a starting step in providing preventive care for patients with atherosclerosis. To perform the segmentation this paper introduces a model utilizing a threshold algorithm. READ MORE

  3. 2. Simulated cerebrospinal fluid motion due to pulsatile arterial flow : Master Thesis Project

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jesper Hägglund; [2021]
    Keywords : Computational fluid dynamics; Fluid structure interaction; Pulsatile flow;

    Abstract : All organs, including the brain, need a pathway to remove neurotoxic extracellular proteins. In the brain this is called the glymphatic system. The glymphatic system works by exchanging proteins from interstitial fluids to cerebrospinal fluids. The extracellular proteins are then removed through the cerebrospinal fluid drains. READ MORE

  4. 3. Segmentation of the Common Carotid Artery from Ultrasound Images using UNet

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Oskar Friberg; [2020]
    Keywords : MSc; Deep Learning; CNN; Computer Vision; Ultrasound; Carotid Artery; Technology and Engineering;

    Abstract : The common carotid artery (CCA), the artery that supplies our brains with oxygen, is of great importance in stroke research. The usual way to monitor the artery is by using ultrasound (US) imaging. An automated way of segmenting out the arteries from the US images is desired to optimize research. READ MORE

  5. 4. Geometry dependency of cerebral arterial pressure, and estimation of wall shear stress in patients with carotid stenosis: a CFD approach

    University essay from Umeå universitet/Institutionen för fysik

    Author : Josef Odevik; [2020]
    Keywords : Carotid stenosis; Geometry dependency; Arterial pressure; Atherosclerosis; Wall shear stress; Computational fluid dynamics; Karotid stenos; Geometriberoende; Artärtryck; Åderförkalkning; Skjuvkraft; Numeriska flödesberäkningar;

    Abstract : This thesis have investigated how the cerebral arterial pressure can be estimated using computational fluid dynamics (CFD). Specifically, a sensitivity study of how the blood vessel diameter affects the arterial pressure in patients with carotid stenosis, has been conducted. READ MORE

  6. 5. A Study of Vascular Plaque in the Carotid

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Victor Thun; Kristin Salmi; [2018]
    Keywords : ;

    Abstract : In 2015, cardiovascular diseases caused the death of 17.7 million people - 31 % of all deaths globally - making it deadlier than any other cause.Cardiovascular diseases often result from Arteriosclerosis, a disease where plaque builds up and clogs arteries. READ MORE
