  2. 11. Optical Coherence Tomography for Dermatological Applications

    Author : Jakob Borup Thomsen; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; medical imaging; skin cancer diagnostics; optical imaging; blood flow; treatment monitoring;

    Abstract : Optical coherence tomography (OCT) is a non-invasive optical imaging technique providing approximately 10 micrometer resolution of tissue in vivo. Within ophthalmology, OCT has already proven its value and is routinely used for diagnosing retinal diseases. READ MORE

  4. 12. Ultrasonic Quantification of Skeletal Muscle Dynamics : Feasibility and Limitations

    Author : Frida Lindberg; Lars-Åke Brodin; Christer Grönlund; Tomas Jansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrasound; skeletal muscle; intramuscular; dynamics; Tissue Doppler Imaging; Speckle Tracking; strain; quantification;

    Abstract : Pain and disorders of the human skeletal muscles are one of the most common reasons for medical consultations in the western countries today and there is a great need to improve both the understanding and treatment of several different muscular conditions.Techniques describing the muscle function in vivo are often limited by either their invasiveness or lack of spatial resolution.

  5. 13. Development and evaluation of non-invasive ultrasonic methods for arterial characterization

    Author : Anders Eriksson; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Instrumentation technology; TDI; Tissue Doppler imaging; Arterial characterization; Non-invasive; Flow generation; PWV; Pulse wave velocity; Mät- och instrumenteringsteknik; Ultrasound; Vascular impedance;

    Abstract : As cardiovascular diseases have been the most common cause of mortality in the western world for decades, the demand for appropriate diagnostic methods is obvious. To facilitate the examination non-invasive methods are preferable since they do not require sensors within the circulation system. READ MORE

  6. 14. Ventricular Long Axis Function: Amplitudes and Timings : Echocardiographic Studies in Health and Disease

    Author : Frederick Bukachi; Anders Waldenstrom; Derek Gibson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler Tissue Imaging; Ageing; coronary disease; left ventricular function; atrial contraction; electromechanical function; coronary angioplasty.; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

    Abstract : Background: The ageing process not only increases the risk of coronary artery disease (CAD) but also complicates its diagnosis and treatment. It is therefore important to understand the newer concepts of cardiovascular ageing physiology as well as methods of predicting the outcomes of therapeutic options available for the elderly with severe CAD.

  7. 15. Quantitative echocardiographic methods for patients with acute coronary syndrome

    Author : Carl Westholm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Tissue Doppler;

    Abstract : Background: The aim of this thesis was to evaluate two diagnostic and two prognostic quantitative echocardiographic methods for patients with acute coronary syndrome (ACS). Methods:
Velocity tracking (VeT) presents the longitudinal tissue Doppler velocities of the left ventricle (LV) as a bull’s eye plot giving an easy three dimensional understanding of both the global and regional function of the LV in regard to longitudinal velocities, systolic as well as diastolic. READ MORE
