  2. 1. Testing of Doppler Ultrasound Systems

    Author : Andrew Walker; Per Ask; Ivar Ringqvist; Bengt Wranne; Birger Wandt; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Blood and tissue velocities are measured and analyzed in cardiac, vascular, and other applications of diagnostic ultrasound. Errors in system performance might give invalid measurements.We developed two moving string test targets and a rotating cylinder phantom (Doppler phantoms) to characterize Doppler ultrasound systems.

  4. 2. Ultrasound Doppler Based In-Line Rheometry - Development, Validation and Application

    Author : Johan Wiklund; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; Livsmedelsteknik; Technological sciences; non-Newtonian; Chemistry; Kemi; process control; In-line rheometry; Doppler; process monitoring; ultrasound;

    Abstract : The trend within fluid industry is towards continuous production, leading to an increasing demand for new and improved methods that allow real-time monitoring of quality parameters and fast process control. The consistency and viscosity can be described by fluid rheology and are frequently used as quality control parameters. READ MORE

  5. 3. Quantification and Visualization of Cardiovascular Function using Ultrasound

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

    Abstract : 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. READ MORE

    Author : Andrew Walker; Per Ask; Ivar Ringqvist; Bengt Wranne; Monica Almqvist; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Blood and tissue velocities are measured and analysed in cardiac, vascular and other applications of diagnostic ultrasound. Errors in system performance might give invalid measurements.We developed two moving string test targets (“Doppler phantoms”) to characterise ultrasound Doppler systems. READ MORE

  7. 5. 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.
