  1. 1. Characterization of Carotid Atherosclerotic Stenosis on Photon-Counting Computed Tomography

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : My Celander; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction and aim Atherosclerotic stenosis located at the carotid bifurcation accounts for 10% − 20% of all Transient Ischemic Attacks (TIA) and ischemic strokes, which occurs when Atherosclerotic stenosis, or so-called plaque, ruptures. The current method to evaluate carotid atherosclerotic stenosis is to measure the degree of stenosis. READ MORE

  3. 2. Coronary Artery Plaque Segmentation with CTA Images Based on Deep Learning

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Zhang Shuli; [2022]
    Keywords : Coronary Plaque Segmentation; CTA image; nnU-Net; FCDD; Anomaly Detection; Koronarplacksegmentering; CTA-bild; nnU-Net; FCDD; Anomalidetektering;

    Abstract : Atherosclerotic plaque is currently the leading cause of coronary artery disease (CAD). With the help of CT images, we can identify the size and type of plaque, which can help doctors make a correct diagnosis. To do this, we need to segment coronary plaques from CT images. READ MORE

  4. 3. Material decomposition using a photon counting X-ray detector in low energy range

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Rasmus Solem; [2021]
    Keywords : Medicine and Health Sciences;

    Abstract : Material decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. READ MORE

  5. 4. Atherosclerosis - A finite element study of plaque distribution and stability

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Paul Lidgard; [2017]
    Keywords : Atherosclerosis; Plaque; Stability; Finite element; Technology and Engineering;

    Abstract : Atherosclerosis is a chronic disease of arteries. Cardiovascular diseases, of which atherosclerosis is an underlying mechanism, are the most common causes of death globally. The disease is characterised by lipids having penetrated the intima of the artery wall, accompanied by inflammation, fibrosis and endothelial hyperplasia. READ MORE

  6. 5. Distribution of Sca-1+ cardiac progenitor cells in the healthy and the post-MI heart

    University essay from Institutionen för klinisk och experimentell medicin; Hälsouniversitetet

    Author : Jonas Christoffersson; [2012]
    Keywords : Myocardial infarction; cardiac progenitor cell; regenerative medicine; immunohistochemistry; laser scanning cytometry.;

    Abstract : The myocardial infarction (MI) is one of the leading causes of death in the world today. Accumulated atherosclerotic plaque occluding cardiac blood vessels results in a lack of oxygen supply to parts of the heart, and consequentially the death cardiomyocytes. READ MORE
