  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. Implementation of Super-Resolution Ultrasound Imaging for in Vitro Experiments

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

    Author : Kani Yara; [2022]
    Keywords : B-mode; Localization; Microbubbles; Poly-Vinyl-Alcohol; Tracking; Verasonics; B-mode; Localisering; Mikrobubblor; Poly-Vinyl-Alcohol; Spårning; Verasonics;

    Abstract : Ultrasound imaging systems are a safe and affordable imaging modality with the disadvantage of low spatial resolution, especially for assessing smaller vessels. However, with the implementation of super-resolution ultrasound imaging techniques, studies have shown promising results in achieving a resolution below the diffraction limit. READ MORE

  4. 3. 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

  5. 4. Image Contrast Enhancement using Poly Vinyl Alcohol Microbubble Response to High MI Ultrasound

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

    Author : Mohammed R. A. Rashid; [2018]
    Keywords : high MI ultrasound; microbubble; PVA; mechanical index; Verasonics; contrast enhancment;

    Abstract : The induced rupturing of Poly Vinyl Alcohol (PVA) microbubbles with high mechanical index (MI)ultrasound beam is used in multiple medical application such as drug delivery, image contrastenhancement and perfusion imaging.In this work, Triggered imaging technique with subtraction algorithm is used to enhance themicrobubble’s (MB) contrast over tissue (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
