  1. 11. Patellar and Achilles tendinopathy : sclerosing injections and ultrasound guided arthroscopic shaving

    Författare :Lotta Willberg; Håkan Alfredson; Jerker Sandelin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arthroscopy; jumper’s knee; sclerosing injection; tendinopathy; ultrasound; Orthopaedics; ortopedi;

    Sammanfattning : Chronic painful tendinopathy is a common cause for elite- and recreational athletes to stop or decrease the level of their sports activity. Recent research on innervation patterns, histopathology and possible pain mechanisms in tendons has led to an increased knowledge about the chronic painful tendon. LÄS MER

  3. 12. Experimental verification of tomographic measurement methods in ultrasound

    Författare :Monica Almqvist; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne.; high resolution; characterization; tomography; light diffraction; doppler; ultrasound; vector tomography; Instrumentation technology; Mät- och instrumenteringsteknik;

    Sammanfattning : This thesis describes two different measurement methods applied to ultrasound. The first method, Ultrasound doppler vector tomography, uses ultrasound to measure blood flow and the second method, Light diffraction tomography, measures the pressure field in an ultrasound beam with laser light.

  4. 13. Vascular ultrasound for the assessment of carotid atherosclerosis

    Författare :Davide Vanoli; Per Lindqvist; Christine Kremer; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ultrasound; Plaque; IMT; Atherosclerosis; CEUS; Carotid vessels; cardiovascular disease; hjärt- och kärlforskning;

    Sammanfattning : Background: Atherosclerotic cardiovascular disease (CVD) is a common cause for mortality globally, and is expected to remain the single leading cause of death as the global population ages and as life expectancy increases.Cardiovascular screening models have been developed, and continue to be developed, to identify individuals at high-risk of CVD.

  5. 14. Dynamic Programming for Ultrasound Image Analysis of Atherosclerosis

    Författare :Peter Holdfeldt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atherosclerotic plaque; ultrasound; classification; dynamic programming; carotid artery; image analysis; edge detection; graph cuts;

    Sammanfattning : Cardiovascular diseases, due to atherosclerosis, are among the most common causes of death in the industrialized world. Atherosclerotic plaque composition as well as arterial diameter and wall thickness can be used to predict the risk of cardiovascular disease. These risk factors can be assessed non-invasively by ultrasound. LÄS MER

  7. 15. Quantification and Visualization of Cardiovascular Function using Ultrasound

    Författare :Matilda Larsson; Lars-Åke Brodin; Hans Torp; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound; Tissue Doppler imaging; Speckle tracking imaging; cardiovascular function; visualization; quantification; Medical engineering; Medicinsk teknik;

    Sammanfattning : There is a large need for accurate methods detecting cardiovascular diseases, since they are one of the leading causes of mortality in the world, accounting for 29.3% of all deaths. LÄS MER
