1. Ultrasound Imaging Velocimetry using Polyvinyl Alcohol Shelled Microbubbles
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)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

2. Implementation of Super-Resolution Ultrasound Imaging for in Vitro Experiments
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)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

3. Acoustic Droplet Vaporization : An Assessment of How Ultrasound Wave Parameters Influence the Vaporization Efficiency
University essay from KTH/Medicinteknik och hälsosystemAbstract : Acoustic droplet vaporization (ADV) is a process in which a phase shift of a liquified droplet into a gaseous microbubble, is triggered using an ultrasonic wave. In contrast to utilizing conventional contrast agents in ultrasound, the phase change contrast agents used in ADV can extravasate into tumor tissue, and they offer a greater circulatory lifespan, thereby increasing the potential applications in which they can be utilized.

4. 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)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. Acoustic Characterization of the Cellulose-coated Perfluorocarbon Droplets based on Phase Velocity Measurements
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Today, microbubbles are one of the most commonly used ultrasound contrast agents, since their high compressibility results in a strongly scattered signal. Despite this advantage, microbubbles experience limitations by the decreased stability and large diameter. READ MORE
