  1. 6. Diagnostic and Prognostic Value of Exercise Electrocardiographic Test Variables in Coronary Artery Disease

    Författare :Håkan Kronander; Lars-Åke Brodin; Erling Löfsjögård-Nilsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; exercise ECG test; coronary artery disease; acute myocardial infarction; Medical engineering; Medicinsk teknik;

    Sammanfattning : The diagnostic performance of conventional analysis of the exercise electrocardiographic (ECG) test for the detection of coronary artery disease (CAD) is limited to 70-75%. The exercise ECG test is the most widely used non-invasive method for assessing CAD and even a small improvement in the diagnostic performance is important. LÄS MER

  3. 7. 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

  4. 8. Evaluation of Errors and Limitations in Ultrasound Imaging Systems

    Författare :Mattias Mårtensson; Lars-Åke Brodin; Peter Rask; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical engineering; Medicinsk teknik;

    Sammanfattning : There are binding regulations requiring safety and efficacy aspects of medical devices. The requirements ask for documentation that the devices are safe and effective for their intended use, i.e. if a device has a measuring function it must be correct. LÄS MER

  5. 9. The Balanced Electromagnetic Separation Transducer for Bone Conduction Audiometry and Hearing Rehabilitation

    Författare :Karl-Johan Fredén Jansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; retention magnet; bone vibrator; demagnetization; bone conduction; balanced electromagnetic separation transducer; magnetically induced torque; image artifact; magnetic resonance imaging;

    Sammanfattning : Hearing via air conduction (AC) and bone conduction (BC) are attributed to bethe natural ways of conducting sound to the cochlea. With AC hearing, air pressurevariations are transmitted to the cochlea via the ear canal, whereas with BChearing, sound vibrations are transmitted through the skull bone to the cochlea. LÄS MER

    Sammanfattning : The organisation of fluids in small compartments is ubiquitous in nature, such as in the cellular composition of all life. This work explores several engineering avenues where microscale fluid compartmentalization can bring novel material properties or novel functionality in life sciences or medicine. LÄS MER
