  1. 1. Ultrasound Imaging Velocimetry using Polyvinyl Alcohol Shelled Microbubbles

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ida Johansson; [2022]
    Keywords : Ultrasound imaging velocimetry; ultrasound contrast agents; polyvinyl alcohol; microbubbles; echo particle image velocimetry; Ultrasound imaging velocimetry; ultraljudskontrastmedel; polyvinylalkohol; mikrobubblor; echo particle image velocimetry;

    Abstract : Current research within the field of ultrasound contrast agents (UCAs) aims at developing capsules which are not only acoustically active, but also have a chemically modifiable surface. This enables use in new areas, including targeted drug delivery and theranostics. READ MORE

  3. 2. Development of a Tool for Imaging the Pumping-Out Behavior of Poly- Vinyl Alcohol Shelled Microbubbles

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Stina Hägglund; [2020]
    Keywords : Microbubbles; Pumping-out behavior; Verasonics; Ultrasound; Ultrafast imaging;

    Abstract : For many years, microbubbles have been used as ultrasound contrast agents to improve the quality of diagnostics, seeing that they produce more backscattering ultrasound than blood does. Novel types of microbubbles and increased knowledge about their different behaviors have led to other suggested areas of use. READ MORE

  4. 3. Non-destructive Evaluation of Ultrasound Contrast Agent

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Wendi Löffler; [2019]
    Keywords : ultrasound; microbubbles; contrast agent; attenuation; phase velocity;

    Abstract : Clinical ultrasound imaging techniques can be greatly improved by the use of ultrasound contrast agents (UCAs). While microbubbles (MBs) without shell are unstable and cannot be used for practical applications,a shell produced from biocompatible polyvinylalcohol (PVA) significantly improves chemical versatility and stability.

  5. 4. Subharmonic Imaging of Polymer-Shelled Contrast Agents

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Rúnar Sigmundsson; [2018]
    Keywords : Ultrasound Imaging; Contrast Enhanced Ultrasound Imaging; Contrast Agents; PVA Contrast Agents;

    Abstract : The harmonic generation due to the nonlinear behavior of Ultrasound Contrast Agents (UCAs) must be exploited for improved efficiency when imaging vascular targets in the neighborhood of highly echogenic tissue. One may even further improve the efficiency by focusing on the subharmonic generation of the UCAs, which is an even more exclusive property than the generation of higher harmonics, for improved Contrast-to-Tissue ratio (CTR).

  6. 5. Ultraharmonic Imaging of Polymer-shelled Microbubbles

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Dimitrios Evangelou; [2018]
    Keywords : Subharmonic Imaging; Ultraharmonic Imaging; Polyvinyl Alcohol; PVA; Verasonics; Ultrasound Contrast Agents; Non-linear imaging; Contrast-to-Tissue ratio.;

    Abstract : Ultrasound has been established as one of the most widely used imaging modalities for diagnostic purposes, due to the several advantages it provides in comparison with other techniques. Hence, ways to further improve the confidence in diagnoses provided by ultrasound are constantly being investigated. READ MORE
