2. 1. Perfluorocarbon microdroplets stabilized by cellulose nanofibers : Toward ultrasound-mediated diagnostics and therapy

   Author : Ksenia Loskutova; Dmitry Grishenkov; Anna Justina Svagan; Gaio Paradossi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound; acoustic droplet vaporization; phase-change contrast agent; Pickering emulsion; cellulose nanofiber; Ultraljud; akustisk droppförångning; kontrastmedel med fasförändring; Pickeringemulsion; cellulosananofiber; Teknik och hälsa; Technology and Health;

   Abstract : Ultrasound contrast agents consist of gas-filled micrometer-sized bubbles that are injectedinto the blood stream. Ultrasound contrast agents are an invaluable tool for ultrasound imaging of the cardiac muscle and highly vascularized structures such as kidneys and the liver. READ MORE

4. 2. Experimental verification of tomographic measurement methods in ultrasound

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

   Abstract : 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.

5. 3. Contrast enhanced ultrasound (CEUS) in breast tumors

   Author : Ariel Saracco; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Contrast-enhanced ultrasound or CEUS is a combination of the pharmacokinetics of contrast agents (or microbubbles-based ultrasound contrast agents), the signal processing of these agents and the contrast-specific imaging modality. One of the main objectives of this method is to gather vascular information (from large vessels to capillaries) in different organs or tumors by increasing the signal intensity from blood. READ MORE

6. 4. Magnetomotive ultrasound for nanomedicine : a mechanistic approach to detection, evaluation and safety assessment

   Author : Sandra Sjöstrand; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetomotive; ultrasound; finite element analysis; cancer diagnosis; HT-29; Caco-2;

   Abstract : Cancer is one of the leading causes of death worldwide, but reliable diagnosis and staging can contribute to optimal treatment planning, and is a crucial factor in reducing mortality and maintaining quality of life. Soft tissue mechanical properties are promising indicators of cancer that can be assessed non-invasively using functional imaging. READ MORE

7. 5. Development of Magnetomotive Ultrasound Imaging

   Author : Maria Evertsson; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetomotive ultrasound; molecular imaging; contrast angents; multimodal imaging; sentinel lymph node;

   Abstract : The earlier abnormalities coupled with disease can be discovered in the body, the larger is the chance to survive the disease. Molecular imaging is a growing research field which aims to detect these abnormalities at a molecular level, when the chance of survival is still high. READ MORE
